i have a 1968 ford truck with 76000 org. miles it has a 360 which is running good but i want 400-450 hp and have ben told the 360 is not a real "performance" engine my dad has a 390 with close to 450 hp and he wont give it to me i also have a friend who has a rebuilt 352 that he says usually makes the same power the 390 makes . so should i build the 360 , swap in the 352 or wait till i find a good 390 ( i have a holly 600cfm 4barrel and a edlebrock performer 390 intake manifold.)
Find a 390--from what I've been told here and things I've read elsewhere, you'd be hard pressed, and money-pressed, to get a 352 to perform as well as a 390. If you are starting from scratch go with the 390, they are relatively easy to find and not too expensive and with a little work could easily get the performance you looking for. My two cents
Mercurys had a 410 in 67or 68,they are externally balanced like a 428 and if you are going to use a manual trans a flywheel might be hard to find but if you are going to use a automatic it might be something to look into.
If the 360 block you have is nice just throw a 390 crank, rods and pistons in it. The bore is the same but the 360 used a 3.50 stroke crank same as the 352. G.
68FordTruck, you already have a 390 in the making... or a 410. A 360 block has a 4.05" bore with a 3.50" stroke. The 390 uses a 4.05" bore and a 3.78" stroke so all you would need to do is swap in a 390 crank, rods, and pistons.
If you want to build a 410 (4.05" bore x 3.98" stroke), it's gonna take another part. The 3.98" stroke crank from the 428 is externally balanced so you will need the flywheel / flexplate with the offset counterweight.
Thank you for the help i think i will try to get a 390 out of a boneyard some where but most bone yards just have 80's stuff. any body know of a junkyard around olympia, washington that has 60's stuff or where i might stumble across a 390?
keep in mind that you can make 425 hp out of a 360 with a few $ such as intake heads carb maybe pistons and stuff like that.
m&m jr i am curious has to what i would have 2 do to make 425 hp i already have an edlebrock performer 390 intake manifold and a holly 600cfm 4bbl would this help? cause i have been told the 360 is a "heavy duty motor" do you know what type of pistons my motor came with "stock" cause its pretty hard to make power with dome pistons. and its pretty toughf to find performance aftermaket stuff for the 360 , the 390 and 352 are common so will stuff for a 390 or 352 bolt up to my 360? thanx alot M&m JR that was a big help and im still open for suggestions thanx everyone!!
Everything that I've heard says that parts for 352 360 and 390 will pretty much bolt on to any of them. Even to go as far as getting the Dual quad intake that were special order on 390 and 427. I've been told that these bolt on to a 360 and 352 just like anything else. Something to think about if money isn't an issue
im 15 and working partime and trying to take mechanics the other part. so in mainly working off of old junk car and stuff from boneyards with the occasional mail order from jegs or summit racing. what im doing right now is putting on headers and dual flowmaster exaust that is going to exit about 8 inches behind the front wheel. so after i upgrade the exaust i want to upgrade the intake and carb. i think i will go with a 625 cfm holly and the edlebrock performer 390 manifold that i mentioned above, what do you guys think about that combo? and what would the cheapest and simpleist way to crank out 400 hp (i HATE nos, and dont like EFI)
If you're going with the 390 and that intake setup (although i would suggest a 650-700), if you do an over bore, I forget the exact specs you can overbore a 390, but I believe you can go .60 over, essentially turning it into a 412 or something like that. Overbore, electronic ignition (always better than points), your current intake setup, good valve job, headers, and you should be there, or close enough. If you have pics of your resto, I'm sure everyone one here would like to see them. When the weather breaks here, for good, i should be getting my cars out and starting my work. let us know how you're doing!
i was going to put that set up on my 360 because so far i havent found a 390. what do you think of my exaust? i've heard that where im going to put it in the long run it could damage my rims from the exaust hitting them is that true?
also my tranny is the stock 4sp with the "granny" low and dana 60 rear end. my gears back there are pretty low cause it starts winding pretty high at 65-70mph
dose anybody know the proper name for my transmission thatway i can order parts and other stuff for it?
You can still bore the 360 but I don't know how much and that might be tougher to get your 400 hp out of. Sorry,I don't know anything about the trucks or the 4-speeds. I have C6 trannys in my cars, and they are pretty much frag proof. If you have a clear coat on your rims, which most aftermarkerts do these days, the exhaust could ruin them. Not to mention you might be breaking local noise restirctions**) Some surfing on the net might get you the answers your looking for, and shouldn't you be in school right now?!?:HMMM: Sorry, its the father in me asking
i'm in school right now. but i dont have internet at home so i gotta do al of this stuff inbetween classes thanx for asking!
Also what kind of hp do you think i can get out of the 360 with good heads(maby ported???) 4barrel, intake, headers, electronic ignition, and dual flowmaster exaust? Would flat top pistons help? i THINK it has domed pistons stock.
Well a port and polish wouldn't hurt, but that usually costs some cash. And I ask some guys I know, that know about these things and the consensus was that a P&P job on those head wouldn't worth the money versus what you get for HP. I tend to agree, but I'm the type that thinks that sort of thing couldn't hurt. Flat tops wouldn't help much in this instance either. In some applications it would but not thisd setup. In fact you might run into some clearance probs if you slap a 390 crank(higher stroke) in and put flat tops on it. Again I'm not much of an expert on 360's. By doing the upgrades that your mentioning, with a 390 crank you'll be pushing 400 but not quite. The 360 had a rep for being a dog. I'd say in the 380-395 hp area. Without the 390 crank your prob only adding about 30-40 hp to the stock hp which was in the 325 hp area? Prob not what you wanted to hear, but without drastically changing your combustion chambers (i.e. diff heads, pistons, crank) you're not going to change much just putting a diff intake and mufflers. Someone correct me if this all sounds off.
I have a magazine from LMC truck and they rated the stock 352@208 hp, 360@215 hp, 390@255 hp all stock and with a 2barrel carb. dose this sound right????
I emailed you with some wrecking yards near Seattle that have some FE motors. If you have any questions email me, or leave a thread here. I am not sure if those trucks in the wrecking yards are 352 390 or what. I know they are FE's .
I don't know about the 2 barrel setups, but pretty sure this is how it runs down, or close, with 4-barrels: 352-300 hp 390-350 hp. Not sure about the 360. Like I said, I'm not very familiar with it. I know that my tired 352 4 barrel with get all 4000 pounds of my 64 Gal going pretty good. I won't win any drag races with it the way it is, but it will get me out into traffic when I need to
I think i will put the 4 barrel, intake, headers, dual exaust and see how it runs then and save up my money for some good heads.
Thats the great thing about these sort of things. You can put it together, drive it and always tear it down later when you get bored with it. I think you will be satisfied with that setup, and it should sound real nice too.
I am responding to your questions about potential motors in wrecking yards. There are a few at Pull-Apart in Everett. ONE i believe is actually a 428 motor. I was up there the other day gettting a FE low mount alternator bracket. The truck i got my parts from was a 390. The truck that had the 428 had an engine fire. The top of the engine is all soot coated, with fire extinguisher residue all over it. The fire does not look like it got too hot, fore the thin steel of the hood was not rippled, anything plastic, rubber was melted, but aluminum things were not. I think the heads and short block would be fine. I believe this motor to be a 428, it has no harmonic balancer, with all the pulleys installed. Ya may be able to get it real cheap.
gLuK............. joe .........
Uh huh, I would touch that motor. Anytime thre is an engine fire, it just scream "Warp or Crack Parts" Keep looking man, that sounds like a money pit
68FordTruck,
Try this link and just search on Washington state http://car-part.com/index.htm . I'm in eastern Washington and its hard to find FE parts. When I was looking for a block about two years ago even Spaulding ins Spokane didn't have any and their yard is about 50 acres. Now I have a spare short block that needs rebuilding in case I need another one.
Just saying this, as someone whos put too much money into a 352fe, its not worth owning. If youre going to go fe then go for a minimum of a 390.
Had to chime in. The 360 is an excellant motor to rebuild. side by side to a 390 all things being equal it will be quicker. Both motors have the same bore. The 360 will get you there quicker with a quicker spinning crank.
The downside to the 360 is that there are no good aftermarket rods that can withstand 6000 plus rpms. It is also said not to push a 360 must past 450 hp, as well. It is reportedly known that the 360 rods are thinner and by there nature ( they are a longer rod than the 390) they are weaker.
A 390 can be built to have more horses than a 360. This is true. But, If you are just looking for a really strong and tough, torquey motor stay with your 360. Put the money you would have spent on the new crank and rods and stuff. And put it in your savings account for tires you'll be needing in a mo. or so.

aw man dot mess around with a 360 drop in a 429 or 460 to me there a lot better more torq plus ya dont have to break down half the motor to do any intake work I had a 390 in my old 69 f250 finaley got smart put a 429 sjc in it . I got a old chvy truk to but I sure do love when my old ford make them devout chevy guy hang there head cry I just put that motor in a f 350 one ton you should see there face,s when them dullys lite up and start smokin I may have one old cheve but my hart leans toward my old ford It realy make my blood flow
You can take that 360 of yours all the way up to a 428 with the proper bore, rods, pistons, crank, etc. But as stated that 360 is the exact same engine as the 390 except the stroke, infact you can stroke a 390 to a 410 simply by dropping in a 428 crank. I have a 360 on my 69 and its a good runnin motor, I plan on swapping out the factory autolite 2 barrel to possilby a holley 2 barrel or maybe even an edelbrock intake with a holley 4 barrel. Being 18 years old and not much older than you, I hear ya on the cash but if you look around you can pick up stuff for that good old 360. :3dSMILE:
i have the same problem its a 68 f100 with a grannyed out 4 speed but i got a 9" with 3.70 gears and it used to be a colum banger 3 speed. i have a 360 in mine to with a holley 4 bbr tops out at about 90 or so but its not the top end that wins its the quickness, but i think i'm going to but a c-6 in mine it should be quicker
if it is a stock ford truck it is probably a Np 435 I think, i THINK they use T-98 then Np435 then T-18, I am not the authority on this though.
I liked Birchymm's comment earlier in the thread. The cool thing is being able to do what you can now, and redo it later. I haven't done anything with a 360, but if it's the 4.05 bore, it can make a 390 or 410, as stated above.
But to encourage you, when I was in high school (back when Richard Nixon was in the White House and Uncle Sam was giving away all expense paid trips to Southeast Asia), a friend was given his older sister's '68 Camaro. Actually, she skipped on it, and his dad had to buy it out, so my friend ended up with it as his wages for a year of so on the family farm. Anyway, 327, 2bbl, three speed floor shift, open 10-bolt with 3.08 gears. Not a speedball.
He saved his money, bought a good cam, Edelbrock Torker manifold (at Monkey Wards), Holley 3310 780cfm carb, and a set of Hooker headers. Oh, and a Turbo350 trans that he had kitted to shift hard. It was about the fastest thing in our school, and cost him about half of what he made driving tractor for a neighbor the summer before our senior year.
About two years later I bought my Shelby, and he wasn't the fastest of our friends anymore. He set out to remedy that.
He pulled the engine out of the car this time , bought angle-plug heads, matched a cam and intake for an 8500 rpm target, added the Holley 850, had the thing balanced and blueprinted, swapped for a 12-bolt posi rear end with 4.56 gears, and had the Turbo350 done again. We never got around to racing, but the gears might have got him the lead back, and that engine was sweet. The header spit at idle, the heavy lope, the sound of the loud turbo mufflers echoing off the buildings downtown. Cost him about half of another summer's earnings, but he just kept after it. Nearly 35 years later he still has the car in the equipment shed on his farm, and his daughter is trolling for it.
Shows you can start small (I think he just did the trans, intake, headers, and carb first), and go on from there. Have a great time with it. I know it's over a year since the thread started, so maybe you can give an update on how its gone...
New to this site and like what I see. I just picked up a '66 F100 witha fully rebuilt 352 and 'grannied' four speed. it's all stock except for the wheels and (pretty grungie) exhaust/glass packs. I"m thinking of keeping it pretty stock (rrrrrrright), but would like to let the motor breathe a little bit better. I'm wondering what headers woudl fit a 352 truck and what intake and carb would be good?? I"ve seen Elderbrock has an intake and 600cfm carb, but I"m not seen any headers.
Thoughts??? Also, what other tranmission would be good to swap out from the grannied four speed, or would that even matter???
Thanks
and forgive since I'm new to this hot rod thing, but what does FE stand for???:confused:
Hedman, Hooker and Thrush and many other manufactures makes headers for your truck. (FE's in F100 to F250 in your year.) Check them out in Summit or another Hi-po catalog.
Two posts from two different people within 10 minutes!?!?! That's great!!
Thanks. I"ll check those three brands out, just saw that Hedman has some headers, so I"ll wait for all my new catalog requests to show up and starting adding the dollars.
Ford Edsel......got it.
Thanks guys.......can't wait to start in on Great White. Ideas for paint, engine work and maybe a bit of lowering have already met with 'approval' from my younger siblings.

Dont know if you have made any final decisions as to where you are taking this project. But I am considering parting out my p/u. If you want details i may have parts of interest and am close to you geographically. Power steering/brakes. Sounds like you are wanting a new rear differntial?....gotta rebuilt c-6, and dyno proven engine...
Your 360 has flat-top pistons that are the same as 390 high comp. pistons. Swap in a 390 crank and rods (if your block and pistons are good) . A four-speed overdrive makes a good swap, especially if your truck is as low speeded as you say. They were factory optional in the early '70's. Its a Ford top loader style tranny. A bit of a jump from second to third, but a 390 has enough torque to overcome that. I have one in a '79 Mustang with a 351W and it works great.
