what do you guys think? i know im going to open a can of worms with this question ...lets see what happens.
i have a 83 305 ho out of my old z28 it has 68000 original miles if i was to put new rings and bearings change to a flat top piston a torker cam and tunnel ram with two 390s in a 1600 lb car how you guys think it will run .
Sure,why not.Quote:

As has been said before "you can't polish a turd"!!! No matter what you do to it, its still going to be a weak assed, wimpy 305. If your going to spend the money, start with a 350.
I have an idea.Quote:

HHmmm is right. 329 cubes with std bore. Squares the bore to stroke ratio. Right rod combo and a decent pair of heads, cam it right, should be a little torquer.
I'm going to go on the other side of the fence on this one. I think a 305 would be fine for it as long as you were just out to build a dependable, moderately snappy performing T. Not all of us want or need a scorcher, and I am truly unable to use all the HP mine puts out, and it is just a moderate 350. If I get into it too deep it wants to go sideways, so I would be very happy to have something like a 305 up there.
I understand that if someone is trying to go for as much bang for the buck as possible, it makes sense to start with as many cubes as possible, but look at all of the cars running flatheads and even 6 cylinder engines and the owners get a lot of enjoyment out of driving them. Even the cars running 4 cylinders, like the track T JRobinson is building, are a blast to run around in and perform great in traffic.
So my vote says use it. You can't tell a 283 from a 350 unless you are really up on the slight differences, so a sbc is a sbc. Dress it up and have fun. :3dSMILE: :3dSMILE:

I agree with Don on this one. The 305 would make a nice little cruiser and if you are going to put it in a light weight car like a T it should have more than enough power for some red light challenges (just don't bet the farm on it):LOL: . After all you don't really need a double plug blown hemi to push a T or an A down the road. Unless you want to.:LOL: :LOL:
build it light enough any anything will go fast :LOL: :LOL:
thanks guys, this is my first T and from what ive been told from other T owners [ you dont need that much power for it to scare the poop out of ya],im gone to stick with the plan and stay with the 305[it might keep me from getting killed]1600 lbs with motor and trans,yea thats lite.will it[305] handle two carbs with progressive linkage, for cruisin to meets?
Two fours will obviously not be as good as a single four barrel, but we all overcarb our rods for the cool factor. If you play with jets you should get it to be very reasonable performance wise. As for performance, honestly it is hard to use much in a light, short wb t bucket. I got my foot deep in mine coming out of a rest stop to merge with traffic on I 4, and the upshift to 2nd lit em up and scared me a little. In normal driving you won't even get into the secondaries.
I like the idea that you have and know the history of the engine too, that helps a lot. Keep us posted.
Don
thanks guys
at 1600 pounds with street tires, especially the usual exaggerated big and little tire combination on T-buckets the LAST thing you want is a whole ton of horsepower.... For 1600 pounds the engine you describe IMO would be very practical and very driveable....
Here's some interesting numbers to ponder...... According to my Virtual Engine calculator, a 275 horsepower engine in a 1600 pound car with the right gears, tires, and suspension should run 11.01 @ 122 in the quarter.....The same horsepower (275) in the usual 3600 pound street car will go 14.43 @ 93 in the quarter....A lightweight car is still the cheapest way to build performance!!!!!!!
I actually did this before. I used a 400 crank in a 305 with an 030 over bore and made a 334. It was a good running engine. Speed-O-Motive used to sell a rotating assembly for this swap. I did it because of the emision inspection that we had here at that time. They always pulled me aside and checked everthing on my vehicle because it was a tubbed pro-streeter.Quote:

I am running a 305 in the roadster pickup.----mainly because I bought the whole damn car for $200 when I was looking for a Chev V8 to build the roadster pickup around. I really, really, wish I had a ton more horsepower. That old engine runs sweet, never gives me a moments problem in 3 years of regular useage, but Jeez, sometimes I miss that "boil the hides, gut wrenching, throw me back in the seat" acceleration that I've only previously found in a built 327 or 350.---Brian
For a street car it is really a good combo.Quote:

It seemed like it worked very well.
I'm a firm believer in using what you've got laying around. No sense in letting a good engine go to waste as long as you're going to be satisfied with it.
That was my thinking too. He has the motor and knows the history of it. With a little internal clean up and some dress up goodies, it will make him a fine motor. Then, down the road if he decides he wants more zip he can build a 350 block and it will bolt right in.
I essentially did the same thing with the 350 in my T. Had the machine shop hone and clean things up, did a ring and bearing job, and was good to go. Runs like a top and is as much as I want or need.

Keep the 305 heads the 3.48 crank for as a spare . Save all the covers . Then find and buy a good 350 short block from your local Craigs list for $75.00 . I did and now have a much better engine ! A 305 has way to small of a bore to build it . A 283 or 307 is a better engine to build with its larger 3.875 bore .
I gatta chime in on this ,.....I built a 305 ,I got mine with less than 3000 miles on a fresh rebuild for 75 bucks..............:eek: No one wants these motors ,for some unknown reason.:CRY:
I spent a few hundred and built one up to about 300 hp at 5500 and approx 350 ftlbs of torque at 3500.
Hp is HP no matter where it comes from,300 hp is a pretty stout engine ,when comparing that to stock factory specs on any car,almost any car that came from the factory with 300 hp was a heathly runner and well above the average grocery getter.
Basically a stock engine with a .030 bore,a xe 262 cam ,rhodes lifters,edelbrock intake and a edelbrock 1405 600 cfm vac secondary carb.
I have not raced it yet ,but I am pretty happy soo far.
Heres one to ponder ,the 5.0 mustanges were 302 engines ,smaller than a 305 and they never hit anywhere close to 300 hp stock from the factory,.............How much fun is it to drive a 5.0 mustang??????Now picture that with 50 to 80 more hp as most were rated in the 220 to 240 hp range stock.
Here is a vid of my 305..........:3dSMILE:

Its by no means a vette killer ,but I am sure it will be a hand full when you gouge it all the way down and start shiftin on the tree.....4.11 gears help too:D
a 305 300HP is not a bad street engine . But if you took all the parts from your 305 and installed them in a 350 . The 350 would have 375HP 420 torque . I did hear your engine on you tube . It runs well nice job . :)
If you want mutliple carbs, why not 3 deuces? Always looks good on an open engine, lots of performance, but easy on the gas when you keep your foot out of it. Six deuces would be even prettier.:eek: :LOL: :cool:
I always wanted to have a dual quad set up . Two 500cfm AFBs on a Offenhauser intake manifold . Not a cheap set up . But real COOL :cool:Quote:

Yeah I like a two four setup too. Thinking about asking the little woman to put the new Edelbrock endurashine 2x4 set up on my xmas list this year. After she stops laughing, maybe I'll save my pennies and order one next Spring.:LOL: :LOL: Sure would look nice sitting under the hood of the 34.
I had a 1972 Olds Cutlass with a mild built 350 Rocket . That engine loved big carbs . I really wanted to put dual quads on that car .
i must say im very satisfied by the response i recieved from this thread , i thought there would be more negativity , i think its because im using the motor in a t bucket instead of a camaro ,things are looking up and i am going to mildly build the 305 and use it ,thanks
a little off the 305 topic but i just had to post this on here
http://www.youtube.com/watch?v=nBOwf...eature=related :eek: :cool:
Glenn, the only thing that I can add is to follow your dreams. First and foremost, you have to be happy and satisfied with your build. We can all offer you advice and opinions, but you have to satisfy yourself. Regardless of how you go about it, do it right and you will be proud of the end product. Good luck with the T and keep us up to date with plenty of photos.
Thanks mopar34 i am deffinetly follwing my dreams, as a matter of fact every time i go into the shop thier coming to life
You won't find much if any negativity on this forum. Everyone on here is smart enough to realize that we all build our cars our own way, and what suits me might not suit you. We might offer an opinion or two, but when it comes down to it, you are the guy laying out the money and the only one that counts.:) :)
Don
Oh, come on Don---You know I'm a negative old poop!!!:eek: :eek:
Ooops, forgot about you Brian. I altered my first line above. :LOL: :LOL:Quote:

Me and the kid went 305 sprint car racing this summer,he won the track championship. car with driver & ten gallons of alky weighed in at 1742. That motor would hike the front wheels on a good tacky track.
60 over 305 block,stock crank, 6.2 eagle rods, custom flat top ross pistons,total seal rings,550 lift schnieder flat tappet cam, block decked , stock 305 heads #602 ? no port or polish (rules) 184 intakes (unshrouds em) all light weight Fierra valves, Fierra light weight lifters, crane springs & roller rockers, heads milled,stock oil pump,cheap Ebay jap copy nascar style intake,750 holley homebuilt alky carb,vertex magneto. complete motor including machine work, minus fuel & ignition system cost me about $4.500 . I don't have any dyno numbers but I would almost bet ya that motor was class of the field ,a buddy had built a very similar motor with 30 over bore and 5.8 rods for his 305 sprinter he also did the 4 - 7 firing order swap, that one has dyno sheets @ 364 horses ( his word I haven't seen the sheets) but since done by a pro engine shop, cost a considerable amount more than mine. My kid can pull him on a straight away drag race ( I contribute it to the 6.2 rods ??)
We ran 27 shows this season,turned it 7200 rpm and I just finished getting it ready for winter storage, backed the rockers off and did a leak down wich showed perfect,pulled the pan and looked at a couple rod and main bearings and they looked very good although I will put new bearings in this spring. All in all I've been very impressed with these 305's..... Butttt still there ain't no subsitute for cubic inches...
i love the 305 in my 78 firebird. .060 over with headers, .cam = .454 - 290 dur. and otherwise stock right down to the 2bbl. Gets 18 MPG @ 80 MPH, and stomps the hell out of ricer burning punk kids. OH yah, I love shifting into first @ 50 MPH and grabbing a car length, thanks to my 2.41:1 rear end!

WOW!!thats one bad 305, dont think i need all that in a bucket but it shows me theres nothing wrong with a 305 for what im using it for
sorry i dont know how to quote
