Rocker cam equations

[88GT17MA]

Hey guys, I was looking to find out what the lift would be with an F-303 cam (512 lift) and 1.6 rockers would be, and how to figure it out?

.512 no math to do.

Most cam lift specs are given at the valve with 1.6 ratio rockers, if you want to figure what the lift is at the cam divide the no. by 1.6. Then if you want to see what the valve lift would be with 1.7 rockers multiple that no. by 1.7.


.512 / 1.6 = .32 cam lift

.32 * 1.6 = .512 valve lift
.32 * 1.7 = .544 valve lift

Thanks alot....so 1.6 is really like the base rocker....544 sounds like it would be a little to much for the street.
