Hi guys,
been away for a while... had a thought while I was on the road. Would there be any gains to be had by running a solid lifter on a hydraulic cam? Is it possible? would it increase the rpm range by avoiding lifter pump up? Are there any potential hp gains by this swap?

Short answer: Don't do it. The ramps and timing events are different between the two types.

Some lobes yes. . .but most no. You can run a hyd. lifter on a solid lobe. Popular in circle track applications where rules are meant to be bent.

I used to build junkyard bomb engines with a good stock 929 chevy hydraulic cam and use a set of solid lifters on it.

Since a hydraulic cam doesn't have the clearance ramp that a solid grind does, it makes it a really fast acting profile and the result is a big increase in low end thrust.

The cam will only last about 5000 miles if you are lucky.

I wouldn't recommend it for anything other than just plain old playing around with your left over junk.

Three words:

NO NO NO.

Thanks for the advice. seemed plausible, but not practical given the experience of those who have replied. See what happens to the brain when you are deprived of your engine for a couple of weeks?
