I'm not getting the feedback I'd expect in another forum so, I thought I'd post here,...I'd like some input on these incrementals; 1.298 3.75 5.82/118 9.13/148.4 This is friends car, and it runs well no doubt. It is NA, weighs 3350lbs. at the line, 572 wedge -1 Indy's, 2.45 first 727 and a 4.10 gear on a 10.5x31 MT on a 10" rim. I believe there is a solid tenth in ET left by taking these incrementals in account in consideration of Wallace calculators. This is a full-sized mid 60's B-body (not really aerodynamic) But I keep hearing Wallace calculators are not accurate in this case. Your thoughts please, thanks in advance!
