Overlap Triangle
If it’s primarily a street car that will see a fair amount of mileage annually, I can understand the lure of the SFT cam.
The problem in my mind is, there really isn’t what I consider a readily available reliable known quantity lifter solution.
I know of some people who have had good results using tool steel lifters, but I’ve also seen some strange wear issues with them too.
For a roller, I think you made the right call on the lifters, but got bit by the gear.
(I’d suggest a melonized steel gear for the next go around if you stay roller)
It’s a little catch-22 ish.
