All of my engines to date have been hydraulic flat tappets, (Old guy here)

The wiping out cam lobes thing has me wanting to put a roller in my next engine. I will be using a 60's 302 block with a 2 pc seal at 28 oz.

Anyone have experience with the retrofit hydraulic roller cams and lifters that Comp sells?

Would a solid roller be practical for a toy/track car?

Can I get 6500 rpm out of the hydraulic?
