Solid rollers with off set push rod hole issue.

gg408 said

Hey the peeps.
Have a set o BAM solid roller lifters in my SBM with .180"offset pushrod hole on the intake.
Recently damaged 2 intake lobes and the other 6 intake lobes have the same witness/wear marks.
Was wondering if the pushrod offset could be causing this issue.
Has anyone use offset lifters and had issues.
Thx.

Is the cam bearing bores completely paralell vertically and horizontally to the main bearing bores? Are the bushed lifter bores completely perpendicular to the camshaft?
A fellow had a real nice Mercury Cyclone with a 429. He had the cam tunnel bored to use the roller cam journal bearings with a roller cam. Did not run long as the shop got the bore off center and the lifter rollers working on the lobes were trying to screw the cam out of the block. Had to get another 385 block and this time just used the std bearings. Costly error.
