Car went down early last fall for a sticky oil pump check valve. Partially tore it down during the fall, but work slowing down killed my drive to do anything since money tightened up.

Spent first half this year so far getting back on track. Finally feeling like I can drop a few K on some upgrades. So......

Before:

377 LS3 Forged Shortblock
APS TT w/LG 70lb turbos
Patriot Stage 2.5 317's
LPE GT2-3 Cam
FAST 102/NW 102
Aftermarket Rails/95lb Injectors/Lonnies Double Pumper

That was good for 825-850 on a rough tune.

New setup

Same Shortblock
Same turbo stuff
AFR 230 V2 Heads with inconel exhaust upgrade
Custom cam (roughly 222/232, .624/.624, 115+4, still working out details)
LS2 TB/Manifold (sold FAST stuff due to leaking issues)
97-98 Return rail, factory lines, etc, Lonnies, 95lb injectors. Rails will be modded for better flow and to fit LS2 manifold.
Melling 10296 pump with blue spring to fix initial grounding issue.

Hoping for 1K at the tires at reasonable boost, but am going to leave the fuel system as the limfac due to not wanting all the aftermarket stuff in the bay. Hoping to be running/tuned by end of September (not ordering heads until July at the earliest).

Just spent a lot of time with my design guy today finally running some solid numbers to figure out what head is going to work best for the setup.

More to come. Car is partially torn down as is, just need to drop mainfolds/turbo's, pop valvetrain out, heads off, cam out to finish tear down.

I also have an LS2 manifold with 97-98 rails It takes a bit of bending to make it fit, but it works. Curious, what's your plan to mod the rails for better flow?

Fastbird

I'm actually having a local fabrication guy work them over. If you look at them, the cups are full size, but the orifice for the fuel flow from the rail into the cup is just a tiny hole. So I'm going to have the bases of the cups welded up then the orifice for the rail to cup opening bored out just to alleviate any possible restriction. He's also going to cut and weld in a new crossover so it's not skewing anything by just bending it.

Good luck with the upgrades Sir!

Any thoughts of the TFS 220 heads vs the AFR ones?

Fastbird

Two big factors. Exhaust side on the heads is better on the AFR, and I can run a stock rocker on the AFR.

C5 Pete

While I don't know the specifics of the exhaust runner for either head, I know you can run OEM rockers on the 220s.

Regardless, sounds like you've got a great parts list.

Fastbird

You are probably right there. I was looking into the TFS 245's and those require an aftermarket rocker.

I you upgrade the valve guides to powder metal instead of bronze you can run the stock rockers on TFS.

how come?
