Got a link?

Erm, nevermind. Colorful description, I'd say

Price seems a little steep. For stock or solid lifters? Anyone want to tell me what the H is the difference between cams that require either hydraulic or solid lifters and why there are even 2 types of lifters?

I hope I get this all correct:

Hydraulic lifters utilize an internal spring and the engine's oil pressure to maintain their dimensions. They self-adjust to thermal expansion and wear, due to the hydraulic action taking up the slack. At high RPMs the hydraulic action can't fully keep up with maintaining the dimensions of the lifter and the valves can "float", or not close entirely.

Solid lifters don't have this problem, as they're a block of metal. They have to be set up with a certain amount of play (lash) to allow for the expansion of the lifter as it heats up. This creates a lot of clattering noise until the engine is up to operating temp. Solid lifters also require regular adjustment to maintain the correct lash, as they have no hydraulic action to take up the slack of wear, loosening, and the various other things that happen to a valvetrain.

As for why the cam must match the lifter, it has something to do with the profile of the lobes on each type of cam. Off hand I couldn't tell you what it is about the specific geometry required for each type that makes it work.

To those in search of some low end grunt, these will big time. Though I don't see them on ebay, $400 is about the limit one should pay for used cams.

Search for "ca18".

If you check out dyno charts of different engines, you'll find that 256's are the best for some while 264's are better for others, while maintaining about the same revving range. For example, I saw comparisons of 256, 264, 272 and stock cams on a supra and the 256 and 264's made huge gains, while the 272s saw lower power all around, even up top since it wasn't going much higher than 7k rpm. Dee's dyno w/ the 264's suggests to me that the 264's are the cams to get, but the 256's still may offer higher low end with very little loss up top.

Thanks, I just bought em.

I think the price is fair considering shipping charges are very low and I dont want to wait around for a special order from Japan for a new set of Tomei cams or something. Im also pulling my motor out for a water pump and turbo change so its a good time for me to swap the cams out.
