Seat to seat, anyway... I think the .750 roller (R286/500) was 286 @.050 which is still a lot of duration. work
iagree up
I like to buy and use a lot of solid roller cams that have between 250 to 270 @.050 with as much lobe lift that I can get and run tighter LSA on the custom ones I have made for special motors devil grin up
An old Mopar sponsored drag racer told me years ago to focus on the first 100 Ft. of the track and the rest of the track would take care of itself. That advice has worked well for me up
Tighter LSA help the bottom end, wider LSA don't work
