SBC SWAP IN A 64 BARRACUDA?

Looking to graft a 64 Barracuda to a 68 corvette frame 1st, then install a 350 SBC and M21 4 speed.
It's a FI unit, roller, 450+ HP.
Will the 8.75/3.55 rear hold up with 15×29" drag radials?
Has anyone attempted a swap like this?
Yup. It'll hold up to most any use I can think of. If you have any reservations, just use a Dana 60 or Ford 9", but IMO, the 8.750 will get the job done.
