Both fun on the street, but not efficient with 4.89 gears and a 4-spd manual. Both had the '71 Road Runner sideways a lot.

Wow, gotta say those are impressive numbers for a low comp motor with a small roller XR292R especially as the ivc on that is at 72 deg. making your CP somewhat low and with only .588"..... I built a 440SP motor back in the day in a similar vein with an 850DP (inferior), Team G int. (crap), 906 bv heads probably not much more than 260cfm (inferior), Comp Cams SFT .650/.650 [email protected], factory bottom end, approx 9.8:1 CR, HV pump external oiling and could only manage 490hp worked out on weight/mph, I was on the right path though I think?...the weight of those rods/pistons in an SP motor is enough to kill the hp....1100/900gms per hole if I remember correct.
