solid lifters

[kwhauck]

I did search but most posts seemed older, I was wondering if anybody had used solid lifters, or what the general concensus was on them.........I am already going all out on everything else so I was thinking I would run solid lifters as well...

thoughts? opinions? Any help would be great!!!

yah...dont run them. if you want lifters like that, use mechanical roller, you will get too much lost effort on solid lifters...better off with the hybrid LT/LS/3400 lifter setup. if you want to turn crazy rpms...doing that spring swap will help, but you dont want to run too radical a grind on a solid lifter, they wont stay on the profile. running a mechanical is prob the best balls out move, but then you even more attention to detail and IMO using the hybrid hyd lifters is just the better decision.

You'd have to use a solid cam for those lifters if its a flat tappet, if you have a roller cam already then it should be fine with solid rollers.

Hi there!

A while back (a year or two?) there was a concern about running solid roller cams on the street. Something about beating the lifters to death, or oiling issues, or something. i don't remember, but it was all over the car rags (Chevy High Performance, etc.) The advice was to keep a constant watch on your valve lash, and if it starts to change a lot, replace the lifters.

Anyone actually run a solid roller cam on the street (any engine, not just a V6/60)? How well did it live?

they work really well, but you must use an oil additive to break them in or use diesel oil because the new oil formulations to not have the additives they used to and you will wipe a cam lobe in a couple hundred miles...i dont like em because they are too much maintenance and too noisy and you cannot run the newer style lobes on them

Ive ran a solid flat tapp cam on my 327 on the '65. I'd have to ajust the valve lash every 1K miles not because of wear but because the locks on the ajust screw kept walking out. I had screw in studs, guide plates, cheap mr. gasket locking nuts. It was noisy. Didn't keep it that long (4months) since my vacume signal was too weak on that cam. Switched to a hydrolic again till the engine died.
Can't tell you about longitivity.

Curtis was running a solid roller in his Z24... It held up fine.


but for more radial profiles in a street car, do what i did with the hybrid lifters and a regular roller cam. I gained some idle vacuum and idle quality, my brakes actually work now which is a plus and i still get full cam lift when i need it.

yes, that seems to be the general consensus, I believe the hybrid setup is the way to go....
