Thread: 460 vs 454

Tweet

That was merely an example! The OP needs to decide a direction and a set of goals for the project. Most everyone daydreams of building a monster cubic inch with huge horsepower, but it isn't practicle!

But you can find a large cubic inch motor, freshen it up and add some select hi performance parts and still have yourself a good time with reliability!
Find a big block with transmission saves you from searching for parts later sometimes. Just another opinion!

He is going to have a considerable amount invested in just the core engine-----------bigblockchev 454 are getting scarce at decent prices---we buy many CORE blocks, but they are just that--cores--we then need not only ALL the performance part/components, but also all the bolts, oil pans, front covers, cam retainer plates, etc,etc,etc


A 460 ford/Lincoln complete might be much easier to find complete and a 460 would be a 4V type engine with a excellent rodlength/stroke ratio and bore/stroke---also pretty good flowing heads--a 429 2V like in that CL add I wouldn't haul home except for the trans, alternator, etc, etc-------

alot of RV i been told get totaled out as they do not make parts for very long and costly so they go threw auction some what cheap many do not have many mile.s on them so you get every thing lets say a 454 many are 4four bolt mains not that you need that so if lucky it would be only a hone and polished the crank and rebuild with a flat top or small dome if it had 049 or 781 heads can be reworked and cam intake . headers 500 hp EZ . as for the big stroker engine deal well many may not need them .but many want them i built more 489/496 then 454 .cost is the same and i sell more bigger engines 489/496 then a 454 thats 060 over 468 if you use cast parts same build price as a 454 about the same for the fords. to bad you do not live around here i could used a hand at my shop you sound like you want to learn that very rare nowdays .as for cheap builds i did many of them .i have core 454s that i could short block for a fair price . new bore .rebuilt truck rods Arp bolts new hypper flat tops speed pro . cast crank GM or eagle .but would be almost 2000. of you 2300.budget it would be a 454 bored over .030 or .060 for $300 more it can be a 489.or496

YESS I AM EXTREMELY EAGER TO LEARN i have a few great guys around here who told me they would help me this summer with whatever i cant figure out and i will help them on their summer projects. the main reason i want to do this is to learn for a day when i can build my hot rod. but if i come into the issue of finding parts or seeking advice may i contact you one here? i dont mind putting more than 2400 in this build, it will just take a bit longer but i would rather do it right the first time, and if im lucky when im done i will have a wild motor ready to go but whatever i get i will post pictures and mark my progress on here, from takedown to paint i will do my best to post it all.

Pat-----------just picked up a Kwik way FWS2 boring bar to use from surface plate on bell housing mount to rough bore the billet splayed bolt caps before align honing----------got a friend with a shop who does that on a lot of industrial type blocks so I'm going to try it on these caps/blocks---I'll let ya know how it goes---when it gets warmer so I can work----

DMC tech /sunnen sold a upright line boring bar that center on the bell sunnen rep told me they did not sell many but did not takeup much space . i done many line bore jobs with the tobin arp T/A 14flat top with the lacey willams cutter bit it can do a very nice finish. the T/A set up mic only reads .0005 so getting under that .what i done many times .you can not have any one in the shop and you must become one with the mic there not much feel with the mic i blue it so i know were i at by the mark the cutter mark

hey a friend of mine has a 454 that is in a generator of his and it only has 30 hours!! also it has a 4 bolt main, i was wondering what a fair offer would be?

I have a '75 460 on a stand that I'm not going to use. Needs new bearings and a new timing cover + new front engine drive, as the old system is for a lincoln and is clunky. I have all the old parts tho.. Also have a C6 Automatic to fit it, or a bellhousing for a 400 that would fit a 3/4spd if you used a 390 flywheel.. I put a new oil pump and pickup in it, as well as an OEM Ford Racing Mustang conversion oilpan ( pickup too )... I'd let everything I've got for it go for $600. I spent a ton more than that collecting the parts, but I'm never going to use it. I was going to build a 501 stroker and decided it was too much engine for the chassis I was putting it in..

If you want the scratch built rat project it was supposed to be for, I can let everything go for $1,500. I don't have time to work on it anymore. If your from Lake George NY, than I'm only a couple hours away in the Catskills.

I will give it some thought but you said you wanted to make a 502 stroker if I get this 454 at a good price I wanted to bore it out to 500+ but I will consider this 460 thanks

you got going to 500 with a 454 cheap . 4.310 bore crank 4.250=cid 496 ....4.310 bore crank 4.375=cid 510 this as a custom piston . you can get the bore bigger then 4.310 get it in a 100over bore not all gm blocks are going to take this over bore

Ok but do you know what a fair offer would be on the 454 with a 4 bolt main and 30 hours ?

i really do not like to post on a open form what the cost should be for you .as i do this for a living i will not pay what many think a good deal for a core rebuilder .as i need to make money to cover my over head. cost for me has to do with many things year of block all bbc after 1990 are mark 5 and 6 engines many parts will not mix and match to older mark 4 parts .need to look at what parts you can reuse .look on ebay for what something like what you want is sold for and CR list and go from there.i did post saying there are parts that may not make 500hp some heads have very small ports and intake and oil pan may not work so then your buying just a short block. that may or not need machine work so then you have more money in the short block then what i could sell you a 489or 496 bottom end for thats all fresh machined and new parts .you need to write this out on paper

460 No doubt. Thats the engine that comes in my mighty 1971 Lincoln Mark lll. Its makes 375hp from factory and with just some tuning and tweaking I easily made 401hp. Change cam,long tube headers with x pipe,port and polish heads,I also shaved heads,aluminum intake,swap gear to to 4:11,lock rear and you got a Chevy killer and 450hp+. I know cause I've done it.

Same engine I have slincoln 3 and for same reasons! Those old Dove heads, and the 10.5:1 factory compression ratio. Hard to beat, for a stock big block. Now if I was real smart one of those new Coyote 5 ltr. Fords(Dave mentioned earlier in this thread) would be the cats meow! Same horse power, lot less weight and better tuning ability, as well as gas mileage!

you can buy a lot of gas for the 460 for what a coyote would cost to install-------
