A mechaical roller cam use a soilid lifter with a roller on the bottom. Litlers are not interchangable between a Mechanical and mechanical roller cam. Mechanical roller is the ultimate race cam. You can run monster lift and duration with the solid roller

Solid Roller Cam engines will generally kill Hydraulic Roller engines as far as power output. Biggest problem with solid roller's are the fact that they are not the cam you will want in a street car, very radical idles on most, no vacuum for brakes. Solid lift valve train will need more maintenance than the hydraulic lift engines. It's all in what you can live with. I personally wouldn't want a solid lift street car as there are some amazing cam grinders out there that can grind you a hydraulic cam that makes nearly as much power as a solid without the headache of having a solid lift cam.

Go ahead and stick a solid roller in your car. It will make good power on the topside like you probably haven't ever driven before. When you go to stop the car from that first 100+mph blast, let me know how the power brakes work out for ya!!

If it's going in an all out drag car, then by all means, I wouldn't build anything but a solid roller engine. I was assuming you were inquiring about a street car. Not that they can't be run on the street, but they will effect power brakes, regardless what Woodsy says. I have seen it happen to many times
If it is going on a street car of yours, do yourself a favor and go ahead and invest in a vacuum canister.

can you give me some more info of a vacuum canister? and how the solid lifters effect brakes?
since all the good brake kits require 17"+ wheels and i got 15 inch weld's with m/t tires and skinnies for the front

There is a link to one on Summit's website. I don't know the science behind why alot of solid lift cams don't make vacuum, I just know that alot of them won't allow the engine to make enough vacuum for vacuum power accessories.
