Valve Lift??

[asecretfile]

on a cam with an advertised lift of .542 int. and exh. if using 1.6 rockers instead of 1.7 how much does the lift change?

Thanks :SNSign:

 

[5spd GT]

.542" lift divided by (current roller rocker) 1.7 = .319" Lift at the Lobe.

.319 Lift at the lobe multiplied times new desired roller rocker (1.6) = .510" lift.

Duration will also take a small hit...

Lift doesn't determine much. At peak lift the piston is near 2.00" down in the bore...

Check for p-v clearance...

Good Luck!
