i think our car is couple hundreths off in the 60ft and about a 10th off in the 330 and about a 10th off in et for the mph. its all Calvert rear suspension including shocks. the front has limiters and some 3 way adjustable cheesy shocks which need replaced but its not in the budget at the moment. my curiousity is to you guys with leaf spring and caltrac cars do the cars like the front end loose or if it hooks do you try to tie it down. i've always been under the impression that if your hooking wheel stands aren't ideal but it also seems like i've read that alot of cars run better when you let them fly. car is 69 amx 28x10.5 pro bracket radial, 4.10 gear 5500 converter weighs 3264 it could probably use a 4.56 or more gear but that'll be tested later.
