73 Duster build named Fred

Engine dyno or chassis? I use Wallace a bunch and think it's a reasonable predictor. Instead of sifting thru the older posts I was hoping he/someone could summarize the info. The best I saw was 104 in 660ft so, knowing he probably hasn't eeked all available MPH from it, that's promising depending on the weight.
I’ll put a post together with all of the pertinent info for someone to play with later today.

As for rpm fall back, I’ve mentioned it a few times, I am dropping 1000-1200 rpm’s on the 1-2 shift.
