What are my chances of having a quiet valve train with:
TSP224R cam
Caddi lifters
PRC dual springs/titianum retainers
YellaTerra rockers
Pushrod length checker tool
shooting for .080-.100 preload
LS6 oil pump
??

PREDATOR-Z

Good chance if the preload is right .060>.080 cold or .080/.100 hot.

I would run 7.425 pushrods

Maybe I should try a
VHP #591
DUR @ .004" 286*/ 286*
DUR @ .050" 224*/224*
LIFT .551/.551
OVERLAP 58*

It seems that a lot of the people with valve train noise are running Comp lobes.

I have never heard of yella tera rockers... many people are making huge power on stock rocker arms, they seem like a really nice design. Could the valvetrain noise that people expierience be caused by the "loose" or "sloppy" stock rocker arm fulcrums? I have some 40K milie-ish stock rockers that are loose as hell.

...oh and both of my 6.0 trucks are noisy as hell, bone stock, one with 60k and one with 80k miles.

I own terra yellow rockers..... they have been on 4 years - no issues. ... a full roller rocker with roller tips...

...needle bearing in the GM stock rockers spill their guts often....

A lot of people are sending their stock rockers to Harlan Sharp and having them modified. It cost less than aftermarket and they won't spit their guts out after the mod.

So I take it they are not supposed to have any slop in them? Anybody know how much the harland sharp rebuild costs?

There was a thread about Scorpion rockers too. Like TRs, no clearance problems... but cheaper than TRs.

I think the rebuild in just over $250, but don't quote me on that. It might be more or less.
