Right, but cheaper than hydraulic rollers....and not as expensive as one would think considering they are pressure fed.
Bottom line is hydraulic rollers are the cat's butt when it comes to streetability and maintenance, plus the added power.
Solid rollers are coming along quite nicely I think. Pairing a nice grind that doesn't require behemoth spring pressures along with pressure fed lifters brings forth a nice cam option.
Beats the crap out of having to run your engine in a garage at 3000 rpm for 30 minutes waiting for the cam to whittle itself down to pieces.....then rebuilding your engine because all of the metal chips got into the oiling system.
I remember Keith Craft posting that he had an engine eat a flat tappet cam on the dyno. If KC can't do it everytime reliably, then I don't wanna chance it.
They say the new solid roller lifters are rated for about 10000 miles. I'll never put that many miles on my car.
