Welcome aboard thirdgen.org.

We need more details about what you plan on putting in. 3rd gen manual transmission bell housings and flywheels are different from the usual trucks and older stuff. What exactly do you have? What transmission were you planning on using?

 

no high jack intended,what happens if it's a 350 out of a,say,1980ish early 90 truck that was auto and u use the 700r4 that is in the car now?

 

SBC is SBC - it's all interchangeable (to a degree). You just have to get the right flywheel and starter to match.

UNLESS you have a V6 - then you cannot attach a V8 to a V6 tranny.

I myself have an old (late 60's early 70's) 350 block in my car, with factory 700R4, using a 168 tooth flywheel and appropriate starter.

 

the motor is out of a 78 camaro, i plan on using the 700r4 thats in the z28 b/c i do not have the time nor funds to swap a th350. so a 78 roller 350 to a 700r4. . im still here in connecticut, me n my friends have been replacing **** on these cars for years but never did a swap, im pretty sure it should be a gravy swap, sorry for the delay in getting back to you guys. but uh yeah, given that these cars were so poorly engineerd, what kind of bullshit might i run into.

 

Swapping is pretty straight forward - much easier in a 3rd gen than many other cars.

Keep the factory carb setup - it will handle the new motor just fine, and it's the best setup you can get really.

 

the 350 has a holley 650 on it, im gonna use that, in the mean time, im building a stroker for it and im gonna line up a th350 with a lockup , but yeah how much can i build a rear on this car

 

It's much easier to build power to break the factory rear than it is to build the factory rear to handle the power you can easily make.

There is a tech article linked from the thirdgen.org homepage about building up the 10-bolt as much as possible. Doing that will run you somewhere around $800-$1100, depending upon what you've got that can be used (maybe a posi carrier, but even that should be aftermarket). Then you can break it and do it over again.

Or, get an aftermarket 12-bolt or 9" for $2000-$2500, and never have to worry about it again.
