Help... BBC piston ????

John Beasaw III · 05-23-2007, 09:18 AM

Does anybody know what the replacement piston is for a 1970 454 360 @ 415 hp. Its not listed in NHRA's list. Or is this a super stock only combo. Classification guide doesnt tell if its ST or SS.

Factored HP seems a little high too. + 55 HP. Whats the big deal. Small valve, oval port, hyd. cam.

Does anybody run this combo in a 70 chevelle.

Thanks
