OK guys my motor has been fighting me every way it can and I guess now I know why...while finally getting the cam in and degreed and buying junk pushrods from indy. I looked at my lifters I see a few where the link connect them there is a hairline Crack in about 4 lifters ....so I'm glad all this has held me up and I checked them....so now I plan to buy new lifters I have 451 lo deck with -1 heads and td rockers ...since I have to buy a new set am I better off getting the offset lifters this time to correct the geometry of the pushrods. ..I know this my change my pushrod length but I have to get new pushrods anyway. ..so what you guys say..

I've used the offset solid roller in the last three high end motors I've built, World block RB B1 with T&D, my own low deck stroker in my Cuda with the Eddy Voctor M.W. heads and the current low deck stroker with 440-1 heads and Jesel rockers Buy the best offset rollers you can afford, straighter angles on the pushrods to the rocker arms is better than more of a angle

If you can get a straighter shot at the rockers by using an offset lifter, do it. Less sideload on the lifters and the rockers. Probably higher/truer lift due to better geometry.

Thanks guys...sgcuda or you close by South gate mall ..I think thats the right mall ..I was up that way a few weeks ago

The offsets out there are all banded and usually need bushed lifter bores so be sure and check that before you buy--on the dyno you can see gains by straighter pushrod angles no doubt.

although a small block, we had some issues that required tear down at 50 passes on our old W5 mill and found four of the lifter bodies with cracks. Called around and spoke with a few knowledgeable folks and nobody had seen this with our Comp rollers. We changed lifters and pushrods and the prob didn't reoccur. Have to believe there was some sort of harmonic issue that caused that.... wonder if it was the same with yours.

If you mean South Park mall, yes. About 15 minutes away. There's a good Chinese food place and a great Italian food place in there.

I ran a set of offset Comp 892. 180 passes at 300/850lbs. One lifter has a worn bearing, other than that the set is intact. There going up for sale.

A basic COMP lifter, is not a GOOD lifter..........it's a mediocre lifter at best. They DO sell a GOOD lifter, but the basic 892s are not them. Now, does every motor out there need an $800 set of lifters?........no, but if the $350 ones are not holding up and have to be replaced.......two sets of those and you have spent enough for the GOOD lifter

At my cam spec and spring pressure it eventually failed one. That's why it got upgraded to Red Zones.
Doug

What spring pressure were you running? Just curious as I recently ordered a set of 892's. EDIT...nevermind, I see you listed that info above. Are some confusing the 829 with the 892 by chance? The 829 is about $450, but not offset while the 892's are offset and around $600 after getting link bars.

Mike at mrl has some nice looking lifters also

Any information on the lunti roller lifters..pros and cons

They were offset 892's
Doug

Every engine failure we have ever had was due to lifter failure. Everytime we have turned the engine over 7800 with crossbar lifters they have died. We ran comp elite. Changed to Jessels keyways and have not had a problem. We are .960 lift 400 on the seat an 1100 over the nose. We now spin it 9200 thru the traps and shift at 9000, 565 in 4.600 bore 4.25 stroke low deck.

FWIW, I run Comp 87019-16 in a MW Victor headed engine. The 87019s are the same as 892s but, Without pushrod oiling. I know they are not top of the crop lifters but, I'm running waaay less spring pressure than some of you guys. PAC 1243 springs.

I NEVER have broken an Isky Red Zone bushed lifter. In fact I had almost 1000 passes on the set in the Cuda at 1050lbs open.

There are many lifters out there. Choose the correct one for the job and all will be well. One thing MANY people neglect is maintenance. Watching or occasionally checking spring pressure and staying on top of lash. If you lash is ALWAYS moving around you likely have an issue with valvetrain harmonics and geometry.

Got a couple that's cracked same place

Why would they break there.............?
