Title: Lifters....
Post by: James Buchan on February 07, 2008, 03:51:08 PM

CB 2 Piece lifters come in two sizes 28mm and 30mm - what goes for what app?

My cam is a SLR XR302 on 110Deg lobe

.529 lift with 1.4's
.473 lift with 1.25's

302 duration

Not going to rev it to the moon, going turbo of course...

I know if I stick with the 1.25 that I have and the lift it under 500 I would be good with the 28mm's, but may want to go 1.4's in the future so should I go with a 30mm lifter?

Thoughts?

The size of the lifter you need has nothing to do with the rocker ratio.  Only the cam lobe determines which lifter you need.
Use the 28mm lifters.

I thought it was partially based on lift... thanks Bruce.
