Push my truck to 7.29 @ 91.73 mph with a 1.535 60 ft. Engine is a very old well used / beaten C3 headed flat top 418 truck pulling piece that I kinda turned into a research deal, has a mix of the old top end/ induction from my second to last 390, street dominator intake, oregon cams version of the 284 B8 comp cam, billet dambest carb, 2 inch header with 3.5 collector into 3" x-pipe. 13 x 31 tall slicks with 4.86 gear last weekend, weather varied from 85-90 degrees, 20-40% humidity, air density was 84-90, the one time I looked my neighbors barometer 29.89... Same trans and converter as always, also wondering what the gonk says it takes to go 7.15 @ 94, 6.90, 6.50, 6.20, and 5.90... when ever you have time is great no rush . Again sorry for loss, gods speed to your dad.
