Which rocker arms?
#42
What kind of lift can I run with stock rockers without upgrades! Do I dare go .555 or will they hit without the upgrades??
Harland Sharp has roller rocker arms for the LS1 Fits 4.8 - 5.3 - 5.7 & 6 L. Direct Bolt on. No machining required. Anyone use them are they worth the $400 for just a cam upgrade?? It's in my 5.3 Silverado wanting to run the Comp Cams thumper 275. it has .553 lift!

That's a pin pulled on a grenade... Stock rocker arms puke needle bearings on bone stock cars all the time.... There's what... 66 or 69 needle bearings per rocker?

Ok sound like good insurance, anyone use the Harland Sharp rockers I can get a set that would bolt on for just under $400, just trying to decide if I want to spend the time changing the Trunions???

I'm running the stock rockers with comp trunion upgrade. Btr .660 springs on torquer v3 cam. No issues after 2 years of abuse on a 150 shot. They even recently all survived a nasty nitrous backfire my ls1 had. The ls6 intake,lid,maf and hood however did not

Hmm T&D makes a shaft system specifically for the TFS heads... PN 20047 which is slightly different than the standard LS1. It includes an offset intake rocker arm. Any reason why they did that? Does that clean up some of the geometry issues on the TFS heads?
T&D seems to include the priority oiling as well as valve spring oiling option, and needle bearing tip option as well, like the Crowers. But from what I saw on YB was to stay away from the needle tip option but get the valve spring oiling option.
