10.5:1. SFT 260/266@.050. nets a touch over .600 lift with 1.6 rockers. It’s drug my 69 roadrunner into the high 10’s with a six pack @ 4000#’s (with me).

I’m building another one right now for a 69 dart. 512 10.5:1 440-1’s with the solid roller from Andy F’s 470. I’ll be curious how it performs.

Cam for the one I’m building.
