whats the total valve lift??

[that national]

since i suck at math and cant figure this out, what would the total valve lift be on this cam 215/220 .516/.529 with 1.65 ratio rockers?

First, what rocker ratio is the cam calculated for?

good question, its the revoultion x cam from full throttle. so im going to guess 1.55 maybe.

Ask them and make sure. Once you find out the rocker ratio used then devide the lift by that ration which will give you cam lift. Then mutiply cam lift by the ratio you want to use to get total lift.

You will have .549" int and .563 ex with 1:65 rockers on that cam.
