Re: cam
The type of lifter used (their is also a solid roller), they are matched to lifter. Just a quick off the top of my head difference, our truck use hydraulic rollers.
Hydraulic lifter use oil as a cushioning, they are more steetable. But the do float float at high RPM's.
Solid lifter are as they seem a solid, a lifter that doesn't have any cushion. Its harsher on the valvetrain (usually require valve adjustment more often) and they are noisier. Solid lifters are better for higher RPM's, they are pretty much require for any sbc or 4.3 reving 7000+rpm (even high 6000's)
Roller lifter (hydraulic or solid) have rollers on them. They have reduced resistance but they also allow faster ramps rates for streetability.
Flat Tappet (what a non roller lifters is, and is solid or hydraulic) have a flat lifting surface, they are cheap and old tech, they also break in with a specific lifter/cam lobe and can not be reused or swapped around.
