Any 10 second "All Throttle" 318's in door cars ?

Doable with at least 11.1 comp, 300 cfm head, solid cam in the 255 @.050 range and a ported single plane.
Probably could get by with a little less cfm head, a little. lol

You can hit 500 HP pretty easy with a GOOD 250 CFM. Probably a bit less than that even IF you get all your poo in one pile.
