Hydraulic roller lifters for non-roller blocks or performance replacements for stock hydraulic roller lifters

When compared to flat tappet lifters, they have less friction and last longer.

Accept a lot more aggressive cam profiles than flat tappet lifters can handle.

Questions & Answers

Will these fit in my 496 build with a 6? Is there a cam that lifts 49 degrees?

If it's a roller cam, I suppose, but I returned the ones I bought because the reviews were negative and the lifters wouldn't pump up.

Lifters that work with rollers

5/5

It performs admirably in an older 454 BBC that has been converted to a roller cam.

"Leak Down Lifters" is a phrase that means "Leak Down Lifters

3/5

" They've been nothing but trouble in my 454 since I put them in. It's nearly impossible to adjust them because they leak down at random. They can leak down even with a weak checking spring. They make a solid lifter sound when the motor is hot. You never know how long some of them will tap away on a cold start before they begin to pump. The best part is that when I told Comp about my issues with them, they told me it was "normal"!.
