Lifter suggestions
I've been getting parts around for a cam swap for a few months now, as my budget allows I buy components here and there. I've already purchased the GM non active lifters, 16, a full set, for my DOD delete and cam install.
My question is should I go with something different? |

LS7 lifters are a popular choice and I run them myself. Unless you're planning on going above 7000 RPM which would require a big cam and proper airflow, you wont need anything else.

LS7, and the L99/LS3 non active lifters are the same? GM part number 12648846 Is applicable in both engines as the non active lifters. |

Yes , from my understanding they’ve discontinued the ls2 lifters with ls7 being the replacement lifter . I went with Johnson 2110 R. From what I’ve read tho most shoot for like .80-.100 pre load and ls7 lifters are .050 taller than stock lifters so your pushrods will be shorter if on stock head gaskett , and non milled heads . Keep that in mind when they try and give you 7.4 push rods , their too short . I suggest picking up a pushrod length checker . Well let me rephrase . Stock cam with ls7 lifter requires shorter pushrods . That length could change with your aftermarket cam as most have a smaller base circle than stock but depends on what cam you go with . A lot of variables , so a pushrod length checker is a must . I’m currently in the middle of measuring all cylinders int/exh soon when I get some time . As per Johnson’s request , thing is I doubt I have that much of a variance but will measure it anyway Last edited by Risingson05; 12-04-2020 at 10:09 AM. |

Just wondering what people do for longevity. I've procured all GM gaskets, lifters, lifter trays. I've pulled a factory valve lifter manifold delete plate form a unsalvageable donor engine. I've got GM replacement head bolts, but will be looking into other options as well, but I don't have much apprehensiveness about the quality of the GM gaskets and bolts, unless that is if someone here knows of some factory flaw that I should maybe look into something else. |

Oh . There’s nothing wrong with oem when it comes to things like that imho. Have you bought a timing chain dampener block ? That plastic tensioner in there is cheap and know to fail . I know mine was broke when I changed my cam |

Ls3 and ls7 lifters are the same. No difference between them. There is no preload difference between an ls3 and ls7 lifter, as they are identical; even in the box of 16.

If you are staying under 7000rpm your good with those lifters.
Like others said. Do your trunions while you got the heads off. I used the CHE Precision kit. IMHO it's the best.

I have not, but I was planning on getting a new timing chain and that tensioner for good measure. Are the trunnion bearing notoriously trash? I'll be honest, I would for a GM dealer, thus I get massive discounts on GM parts, I just want to be reliable at the end of the day, and rocker arms don't seem to be a huge seller. Although we also don't see a lot of performance cars through the dealership either.

The GM needle bearing trunions have caused havoc on many a car. They are not even ok for stock engines. Get the dogbone LS2 chain tensioner too.
