David,

You can run solid lifters on a hydraulic cam, but you can't run hydraulic lifters on a solid cam. The ramps are too steep and you would end up losing control of the valve train.

If you look at a hydraulic roller camshaft, there is a big difference between durations at seat and durations at .050"....usually around 50-60°. On a solid roller, you get differences around 30-40° depending on the lobe. The solid roller cam would be lofting the lifters sure as the world. Hydraulic roller lifters are very heavy, and SBF valvetrain isn't the lightest in the world either.

If you want a nice, smooth solid roller grind, you can go to their "street roller" section. The ramps are smoother, so you can get longer life out of your springs and lifters. If you want an extremely aggressive lobe for a race car, you can use their "TK" lobes. However, your springs and lifters will call you names behind your back.

I use Comp Cams quite a bit for street/stock builds, and I also use Mike Jones for a completely custom grind. I am a distributor for him and have used his cams in my own engines. He says that his grinds are 20-30 hp over comparable Comp grinds.

BTW, how much lash are you running?
