Which flow numbers would you want have and why, the 1st or 2nd? Going into LT1 383 10:1 compression, 246/246 112 ls .600 lift cam, 200 shot. The 1st has better flow at .600 and the 2nd is right behind it there. The 2nd has better flow rates between .100 and .500. Does it really matter to have good flow at your max lift of your cam is it better to have better flow under .500 lift?

 

better for the Lower lift numbers you probably won't see the high lift numbers as Much.....
