The 5.7L 350ci SBC is the best bargain for small block V8 performance in history. Look up what something comparable would cost. You can build a 400+ horsepower 350 for dirt cheap.

Even so, this doesn't mean that the 700R4 is weak.

It was a stupid thing that i did, but if a 3.1 could damage it, a 350 could murder it.

well, not necessarily....


see your own post. lol

that would blow just about all but the strongest trannies. I did a reverse to neutral to 1st slam in my old 78 camaro and the whole damn thing exploded. so I swapped in a 3 spd manual out of my grandpa's old pickup.

how much money do you plan to spend on a full engine build? take that figure and double it to be on the safe side. you could go out and do a turn key motor (but most times they are lacking in power) but you could also spend the time to price various components and ensure they complement each other and build it yourself. you can get a balanced Eagle rotating assy for around $600.00 find you a used block, buy some 4-bolt splayed end caps, and take the rotating assy, caps and block to a machine shop and have them line hone everything and bore it out to a 355. find some good heads and have them ported or leave them stock and a good intake manifold and carb and throw it all together.

go check out some of the muscle car mags on the rack. nearly every other month they have a "budget build" where they make nearly 400 hp only spending about $2-3k.


in fact, I think I have some at the house. I'll dig around for them tomorrow.

yea, wel rite now i got a 2.8 v6 in it, and its fine, but i need to be able to beat my friends '91 mustang, and thts a 5.0 v8, and its stock, so as long as its better than that, im not going to be all tht picky

ah, the lil 2.8 that barely could. the one we pulled from the 86 had about 268k on the odo when it finally gave up the go.


what is your planned budget for this? give me a ball park (realistic figure) and I can run from there.

yea, mine only has 87,xxx on that engine, and i want to spend as little as possible but as long as its good and its worth the money, ill eventually pay watever it takes

well, you need a goal and a budget.


we'll take some things for granted.

you want a v-8
probably 300hp (or more if its not too costly)


how much work do you plan on doing yourself? or how much work will you be capable of? (like bolting on heads, installing a cam, etc) obviously, machine work will be left to the machine shop.

and you will also need a transmission as well. its a shame you dont live closer to me. I have a good friend who builds transmissions for a living who could set you up with one hell of a 700r4 for about $850.00 tho I have spoken to him about freight shipping transmissions to other people in the country.



you can get turn-key motors for anywhere from 3-25k the GMPP ZZ4 crate motor runs right around 5k. and its 355hp.

also, check out Golenengines
http://www.golenengineservice.com/

and swing over to www.thirdgen.org and see some of the swaps that they have done to get some ideas on what to do.

however, you can do a full teardown and rebuild of a small block that you find in a junker car as well.
there's a wonderful book at most auto stores called "How to rebuild your chevy small block"

there's also this one
http://www.amazon.com/Build-Performa...d_bxgy_b_img_b


but the question that remains is how much are you going to do yourself? having someone else do the work will be easier and normally less time consuming. but it will be more costly.

read thru this http://www.carcraft.com/howto/116_03...nes_cores.html
and it will give you an overall guide on what you will be looking at if you go to build the motor yourself as opposed to a turnkey.

well for some of the questions its a 350 from a 1971 chevy truck thats all i really know but will i still be a ble to put it in my car? and will my ten bolt rearend hold up to its power?

[Supercamaro64]

wow, 850 bucks would be great. hey heres an idea, u should move to wisconsin!! lol if i cud just spend less than 1000 on the whole deal tht would be great. ah well, my 2.8 will just have to hold on for a little longer (exasperated sigh)

O, and does anyone know where i cud find the front end of an 86 berlinetta? cuz the guy who had my car before i did smashed a crack in the front plastic part. (he also smashed in the rear left quarter panel) before i got this car, nobody cared about it, which is y its so sad, cuz now i have to do a load of repair work(thankfully not on the engine, tht runs fine, it just doesnt look like much from the exterior yet).

the same way you can have a 350 big block. the differences are not the cubic inches. its the overall block size that determines whether its a big block or small block.

you can bore, stroke, and sleeve a small block to a large size, but it would not be worth much outside of the track.
