Hydraulic Roller Lifters w/LA Block?

sorry to say but that is why later blocks for roller lifters have taller lifter bores. I would not grind the cam for a smaller base circle, not enough lifter support at full lift, when the springs are at peak load. mopars have the big .904" diameter lifters, so they do not need rollers as much as the other chumps. and with the lifters and pushrods at different angles, the smallblock mopar likes lifter support
