Quick cam question

I am piecing together a cam only setup and have a quick question. I have been reccomended the Comp 224/230 cam from a friend and wanted to know if thats rated that with 1.5 rockers or 1.6. Also what would that make the I/E lift and duration with 1.6 and whats the formula you use to figure that out. Thanks

Heres the Link that I was shown for info on this cam.

Your rocker arm ratio is going to change the lift, not the actual duration of the cam... Although I guess you could argue that the duration at .050 would increase because of the change in lift...

Lift would be .536/.544 with 1.6 rockers.

You take your lift number and divide by 1.5, then take that result and multiply by 1.6.


I run the same cam, but on a 114 LSA.
