wondering if there is an advantage to running split ratios 1.6/1.5 or if I would be better off running 1.6 only. cam specs are 675/624 264/272 @ .050 106 Howards cam. 383 sbc 12.9comp massaged Brodix Tr 1's Enderle alky injected. Thanks for any help.

I would run it with the same ratio rocker because your cam all ready has a split between lift on the intake and exhaust. Going from 1.5's the 1.6's gives you about .030 more in lift. And dam your picture is big.

yeah, thought it was the small one, guess not. sorry bout that. Thanks for the info(on both) whats the reason for a split like that? better velocity or just doesnt need as much lift to remove spent gasses? just trying to learn a few things about the most important part of making power...gettin it in and gettin it out P.S. Love the truck

ok, well lets try this question. to determine the difference in total lift I would take my cam spec of .675 and divide by 1.5 to get actual lobe lift (.450) then multiply by the new ratio of 1.6 to arrive at a total lift of .720 which is a difference of .045. This seems logical but I would like to know if I'm missing anything or thinking wrong. Thanks, Zombie
