View Full Version : 1.6 rockers on exhaust
We run a 425 lift rule class new motor is ready all but cam would there be any advantage on a 400 lift cam and using 1.6 rockers on exhaust only it would still check right well within a few thousands I have found a cam I like it's a 400 lift or be best to just get a 420 or so lift cam.

If you have the clearance.you will see better performance by having the 1.6 rockers on the intake.You won't see anything by having them on the exhaust.
1.6 rockers will increase the duration at .050 by a couple degrees.I've used them with good results in classes with lift rules.
