That would be answered by the manufacturer of the camshaft itself. To speculate would be a waste of your time.

A census taker tried to test me once. I ate his liver with some fava beans and a nice Chianti.

No! The lifter bodies are totally different. Not to mention the lobe profile of the cam from roller to flat tappet as well. Don't do it.

08-22-2004 #7dennis68 GuestWhat do lifter bodies have to do with using a solid lifter on a cam ground for hydraulics‘?!?! As for the grind's, hydraulic grinds are much less aggressive than solid grinds, I'd be much more worried about going from solid's to hydraulic than the other way.

The hiegth...Stick a roller on the end, it gets taller. It's not my engine, do what you want to with it.

Brad, unless I misread too, the original question is concerning hydraulic rollers and solid rollers, NOT flat tappets. Besides, any difference in hieght of a lifter body can be accomodated by shorter pushrods.

I may have mis-read that too. I do know going flat tappet to roller is no good. As roller cams are made from billet. So a soft, flat lifter on a hard cam will kill the lifter, other way around willl kill a lobe. As for going from one roller to another roller....let us know how it works out.

Hydraulic roller to solid roller
Is OK. In fact, I have someone doing one right now in a hydraulic appilcation that is floating at 5700. Called the cam company, and they seemed to say, well, you may have to use solids! They recomended the swap to solids. Kind of sucks because they made the cam for 6500 RPM operation, but their lifters only go to 5700? Whatever!
