Please pardon my ignorance, but if it was an absolute must then why do they sell cams by themselves? These lifters seem to be in excellent shape, they're not dished or anything. The reason is I bought a new cam and assumed it was a kit - it wasn't. I'd rather not dish out any extra cash unless they're going to wreck the new cam.

 

yes if it's a non roller hydrolic or solid you need to replace the lifters

The reason camshafts are sold individually is that some builders prefer to use lifters of a different type of from a different manufacturer. Using old flat-tappet lifters to break in a new cam would be a sure way to ruin the tape that is supposed to polish into the lobes.

That same basic question is how I got my 396 so cheap. The previous builder put a used hydralic cam with new mechanical lifters. Made it to the second oil change before there were bunches of metalic particles in the oil.

Yes you can put used lifters in with the new cam, But no, your engine won't last more than 5000 miles.

 

Whoa! Good thing I double checked.

Now that I need new lifters I have another question. I was looking at some different kinds of lifters and found some "Variable duration lifters" which are supposed to bleed oil at lower rpms for less duration and retain full duration at higher rpms. Don't all hydraulic lifters do this - at least to some degree?

 

some lifters are what are called fast bleed, or made to bleed off quickly at low rpm and then pump up again at higher rpm levels. i think crane makes them and i'm sure others do, but i've never used them.

The cranes are quiet, but to tell you the truth I didnt like them. I have a friend who has run the rhoades (or however its spelled) in just about everything and he loves them. They do make some noise tho, but its really little especially in comparison to solids.

Personally I'd stick with some anti pump up lifters and stay away from the bleeders.

 

Crane's are called High Intensity and are recommended by TPIS for their performance. Rhoads is the other company that I know of and their's are louder than the Crane's.

I've run both and, over-all, the Crane's are better because they tap less.
