Drivetrain Upgrades for C3 (77) Vette
Been a long time, but glad to be back. The 427 is progressing nicely as i now have a finished block, crank, and cam. The heads, pistons, and rods were sent away and should e back within a month. after that it's time for assembly! This is really all fine and dandy, but from what i keep reading, it looks like i might get a run or 2 out of the car before i grenade something drivetrain wise...The motor is a clone of an L88 and as such will be producing that kind of power. I know the stock parts will not withstand such punishment for long...what are my options here, and the links to the products? i wanna do this right...and only do it once...

I've had a 500hp 454 in my car for many years now and the stock drive train can take lot of punishment! I haven't ahd a single problem with the drive train, I use my car for all kinds of driving, cruising, autocross and drag racing.
But if you still want to beef up your drivetrain you should contact Tom's Differential. :yesnod:

One thing that will kill the drivetrain is when people sidestep the clutch at +5ooo rpms and havent picked up the slack.That will kill anything..The diff and tranny can take alot of punishment,but the weakpoint is the halfshafts and spindles(sp?) :cheers:

I have abused my stock drive train for 13 years and that includes huge slicks behind a big block. I did blow 3 700R-4's and 4 torque convertors with the slicks but never a drive shaft, rearend or halfshafts. In a recent check of the axles I found them twisted, not broke but twisted , so I replaced them.
If you don't dump the clutch with slicks or power shift most parts will live. If you blow something then replace it.

Re: Drivetrain Upgrades for C3 (norvalwilhelm)
so basically it's just stupid people giving the parts a bad name...for some reason that doesn't supprise me, since so far the car has stood up to everything i've put it through....and being 19...you can bet it's been alot...
