I have to make the decision which kind of lifter to use:
The lobe lift will be over .580" the valve lift will be 1.100"
The came core will be 65mm
Spring pressure will be around 400/1100 lbs...

Up to now I was using Jesel DLC coated only, because of their superior quality and close tolerances.
The possibilities are (all .850 wheel ):

1. JESEL .937 keyway lifter
55426

2. XCELDYNE. 937 keyway lifter
55424



3. Cam FX 1.062 keyway lifter
55425


Thx in advance

Either will work. We have used a lot of Jesel with zero issues. Xceldyne has lifters in 40% of the NASCAR Cup cars so it's proven at least in that arena.

I have a friend running the Xceldyne 937 lifters in his engine with that much spring pressure and so far no issues, last season was his first season using them. When he reworked the engine over the break the lifters looked like new.
