don't worry about your brother's nova, i had a lighter '69 elcamino with a stroker 390 pushing close to 400 to the wheels and my 7 when i was only pushing 270whp was faster than it was with the locker and 315's with the ratchet shifter and turbo 350 with a shift kit.

Sorry to say. You are 100% wrong. I have been racing this same engine/car for over 13 years..I know what I did different and what I didn't. Thank you drive thru!
