Are all roller lifters created equal???

Well I just go my motor back from Jim Kilpatrick and its down to the little items...

The next one on my list are the roller lifters. Its a Comp Roller with a gross lift of .720.

Is there an advantage to spending Jesel amounts of money. or will a standard set work.

Thanks

These work nice

Pushrod oil, press. oil to bearings, oil hole is parallel with axle, shrouded wheel, and top quality metals.

Crowers will live with high spring pressures and are reasonable cost Comp 829-16 lifters can't take the big pressure long at all When you send them back to Comp for the rebuild service ( thinking you will save $$ ) they send back incomplete sets and tell you some were shot--then you are buying a couple of pairs at big $$ and the good deal goes out the window---lots of folks have run Comps without problems but a serious race engine needs the Crowers--on SOME blocks a little grinding or machining is needed--good guy to ask is Todd Marsh 336 752 2879 He told me he had Crowers in stock for an unbeatable deal

Crower and Isky for street cars is all I use.

I run the isky solid body rollers which work w/un bushed lifter bores and am going on 4+ yrs. street strip w/out any issues so far.

The simple answer to "Are all roller lifters equal" is No! But, do you always need to buy the very best---No!

Two things kill roller lifters----spring pressure and lifter float. If you run fairly low spring pressures and always keep the lifter on the cam---then practically all roller lifters will last a very long time. I am installing a 50 year old set of Herbert roller lifters on our nostalgia street rod engine---it probably has 100,000 miles on the track and street---but at lower roller spring pressures and the cam is mild enough to keep the roller on the cam.

What to look for? Roller diameter is one thing, bearing size is another, the size of the bearing axle and how it is attached in another thing to consider. Don't automatically discount any particuler brand roller---Comp has two different roller lifters---one is just OK, the other is very good. Look at the lifters themselves. And the price does tend to indicate how good a roller lifter is.

Jesel produces a very good roller lifter---but not many need a Jesel lifter either. Isky roller lifters are hard to beat---far from the cheapest---but their lifters will stay with you! If you are going to use a mild roller cam/springs, most anybody's lifter will work OK!

My spring pressure is about 350 closed and 830 open. I will look at the crower and the iskys

thanks

That is a lot of pressure---you must have a very heavy valve train. You definitely need good roller lifters!

lifters are on my winter to do list too...
who has the best prices on the isky and crower lifters? big block

When making it boost requires a pretty heavy duty spring. The cam is pretty aggressive as well so I think that came into play.

I will look into these items.
Any other opinions

When looking at the Isky, I recommend the Isky Red Zone lifters. Really nice pieces and I didn't think they were out of line, pricing wise, for what you get. My

PM where you got yours and the price if you dont mind...

If there are any ISKY dealers on here let me know.

I'm an Isky dealer, you can call me. # is on my website. I still prefer the lifters I showed you, we helped Comp develop them...

I'm going w/ Herbert lifters; the cam is an Engle street grind I got from Cab Burge, the springs should have just under 200# on the seat and right around 500# over the nose. I'll check the lifters occasionally and see how they hold up.
