Larry,
Not talking about a cleanup in aisle 3 after failure. What I'm asking is it cheaper to run roller lifters/cam vs flat tappet.
Flat tappet coated lifters are $1248 PPPC (quoted 10/5/2023)
Rollers are around $900 Crower
Cam- A Billet is around 8-9 hundred for Big Block and I wouldn't run a cast cam with the weight of valves and spring pressure in a Big Block if they paid me.
Seems on the flat tappets the coating wears off over time (some pretty damn quick lol) and lifters have to be refinished and coated (if ya catch it in time). Cost quoted was $550-$650 (they have to take the old coating off) for coating and around $5 per lifter plus shipping ($35 with insurance) to refinish, etc.
What's the life on a roller lifter running "stocker" springs and RPM?
