Ok, I have been playing with this idea for a while and was wondering if one of you guys had the ear of a Chrysler engineer. I don't think so but it's worth the shot. I don't want to spend the $3200 to Je$el for solid roller lifters for my Hemi and for .650 to .700 lift and 7500rpm, I really don't need them. I had thought of pulling the guts out of a stock lifter and making an insert for it to make it solid. The problem I am having is the bearings and axles and lack of knowledge about their makeup and materials. Sure I can make them solid but would they hold up in the long run to the abuse. The hydraulic roller has constant contact with the cam so when it lifts there really isn't any shock involved but on a solid cam the lifters get pounded into. I'm going to buy a set of Harland sharp roller rockers and have been conversing with comp on a new cam. (shooting for a stock displacement 5.7L Carbureted Naturaly aspirated engine in the 600hp plus range) and for the people who say you can't do that with stock internals, it dosn't have stock internals. I'm making between 525 and 550 with it now so a cam and intake would probably do it. Any help would be appreciated!!! Thanks!! Joe :joker:
