I got the cam
I got the springs
I got the retainers
I got the pushrods on the way
I am about to order my UD pulley.
I need to order my PCM from Wait4me (should I get it pre-tuned by him?)

Is there anything else I'm missing? It's going in my '02 M6 SS w/ a lid and cutout. I can't afford long tubes right now so i'm hoping I can pick up a daily driver soon or not hurt it without the tune while using the Jet Hot Performance chip that's in it now.

 

oil pump

 

ls2 chain

 

I have heads going in also- so you don't need the headbolts- but here is my list of incidentals from my buddy that's helping me install.

- 2 GM headbolt kits (2x GMPN 12498545)
> >- 2 AIR tube gaskets (2x GMPN 12553617)
> >- 2 Water pump gaskets for 99
> > - 1 front engine seal (1x GMPN 12561244)
> > - LS2 Timing Chain
> > - LS6 Oil Pump
> > - Harmonic Balancer Bolt

 

I wouldnt spend the money on a mail order tune, Id have it done on a dyno if possible.

 

if dual springs, spring seats

 

Dont need an oil pump. But definately I'd go with a chain, I did the LS2 myself. Just make sure you get that Oil Pump Pickup Tube O-ring. Dont reuse the old one, and make sure the new one doesnt get pinched!

 

Replace the valve guide seals while you're in there. Shim the oil pump spring - same deal, while you're in there.
