Technical Camshaft/Lifter issues SOLVED

I need to amend post #17 item 4 to recommended spring pressures may be too high for most applications.
When I built my OT BMC A 1098 engine, I talked with Schneider Csms about spring pressure. The springs recommended were in fact light I’d have to look up the values. I’m sure it was 100lb or less closed. But the cam is fairly aggressive 230 degrees at 0.050 and 0.290 lift at the cam. It will rev to the moon if I wanted to take it there.

I always used a ten minute break in period. Going back to the mid sixties I have always done it that way and never had a problem. I guess I have just been lucky.

 

I would say yes, you are lucky if you get away with it now. Cam profiles, oil make-up, and country of origin manufacturing has all changed.
