Hey everyone, I know I guy that's got a 67 Valiant with a 408 Stroker in it. It has Edelbrock aluminum heads, a Performer RPM Air-Gap intake, 750 cfm carb, 12.5:1 compression with a .610"/.610" lift solid cam, my guess on duration is around 240-250 @.050", 1 3/4" headers.
Valiant I guess weighs in around 3200lbs.
Transmission is a built 727 w/a 4200-4500 stall converter.
4:10 gear with a 28" tall tire.
Car runs 12.70's w/trap speed I think around 110mph at around 6000ft elevation. Not sure, but does that seem a little slow for that kind of motor/ combo??
Converter seems a little tall to me??
I would think at least low to mid 11's.
