How much cam can those chevrolet roller lifters handle.

One area where you must be careful with production-based small-block Chevy hydraulic roller lifters is with high-lift camshafts. According to Crane's Director of Valvetrain Research and Development, Mark Campbell, valve lifts of more than 0.530 inch at the valve with a 1.5:1 rocker can allow the lifter to fall deep enough into the lifter bore (because of the lobe's small base circle) that the steel retainer can lose its grip on the lifter body. This allows the lifter to spin in the bore and destroy the camshaft. In checking a few cam catalogs, it is possible to order a hydraulic roller camshaft with enough lobe lift (in excess of 0.354 inch) to create this situation, so just be careful. This is why Crane created a long-travel hydraulic roller lifter that will allow you to run a high-lift hydraulic roller cam with the stock lifter configuration. These eliminate the problem but are also much more expensive than OE replacement lifters. Another solution would be to run a 1.6:1 rocker ratio with a reduced lobe lift cam to accomplish more valve lift.
