well story goes, i got a vette, engine spun some berrings (damn broken idiot light) and we did a massive rebuild. so the engine is strong as hell, however right now it is just sittin. its getting prepped for paint and body work has been a long deal. anyway i want to paint the engine compartment when i do the color change to the vette, and having a engine sit is bad, so i wana drop it in the 'ol TA. give it some pep (a buttload of pep), and keep the vette engine running at the same time.
my question is: Will a '79 4-bolt main 350, fit a 85' T-5 tranny with little or no problems?
will i need a higher grade flywheel or clutch?
(highly doubt it but) Driveshaft?
the L-82 (vette) has about 350hp at the fly and redlines at 6700. if that helps.

bone stock sloth of an engine LG4
T-5 tranny. thank god, i couldnt stand an LG4 auto.
Plans for an LT-1 or LT-4,
dual flowmaster exaust,
& a pounding stero.
mods right now include a radar detector.

 

it should, the bolt patterns have been the same since 1955 i think.
but... T5s suck a lot, they just cannot handle much torque!

 

as in loss of traction, or breaking tranny? cuz i dont need to break anything that isnt broke.

It will bolt right up as if it was made for the car, except for one detail. You'll need to get a 153-tooth flywheel for the one-piece-rear-main-seal design crank, like from a 83-85 Camaro or Firebird. If your existing T/A clutch is old, now would be a good time to get a new one, and save yourself the trouble of taking it back apart. I have the Centerforce Dual Friction, and I really like it.

You can avoid trashing parts if you restrain the enthusiasm of your test drives somewhat. I have quite a bit more flywheel horsepower than that (400 with a big roller cam) in my daily driver with a T-5; as long as I don't dump the clutch or speed-shift it, the trans is OK. Do either of those things more than a few times and you'll be rebuilding a trans real soon too.

What? Aren't 85 and 79 (the two cars in question) both two piece RMS blocks?

 

You're right 99, my bad... flywheels are the same. He won't have even that obstacle. Should be a slam-dunk.

RB, I'm going to be dumping a 350 in place of the old LG4 within the next while (boy I keep saying this) and I am realizing now the clutch is somewhat bagged. I have an older T5/Clutch setup, ('83) any recommendations as to a decent aftermarket setup capable of handling the ~350ft/lbs I will be throwing at it?

Later,
Hype.
