SBC SWAP IN A 64 BARRACUDA?

Wow a lot of you guys are really closed minded. Why do you care what he does to his car? I’ll tell you this, the last thing I ever care about is whether or not some *** hat at a car show will talk to me about my car. After all I didn’t build it for him.
Will it be better with a corvette frame, engine, trans? Who cares?
OP the 8-3/4 will live behind it just fine on drag radials. Up to the point of launching the car on a transbrake at 5000 rpm with 450hp. Foot brake and mild launches you’ll likely be just fine.
Tried not to sound "closed minded", that's why I pointed out the differences that will need to be overcome- just because he may have the parts doesn't necessarily make it practical, and there may be more viable options out there.
In the end, as I said, it's his car. He can do whatever blows his skirt up. But mainly, he needs to be aware of the challenges he's facing and make sure they're realistically within his skill set.
And yes, the 8.75 can live just fine at those power levels. But I need to ask; if you're using an 8.75, what is the advantage of using the Corvette frame once you dispose of the IRS? Just curious.
