I also got me "eBay" BOV in the mail, I'm actually impressed for $75, although I did order a black one and this one is really dark green:

FIC 1000cc injectors, they flow 95lb @ 3 bar (43.5psi), 108lb @ 4 bar (58psi)... I just told him I wanted 80# injectors and he told me to reach my goal of 700rwhp on E85 I would need at least 95lb injectors so he sent me these LOL:

A little update, I've got the engine put together and ready to go, I ended up installing a Melling High Pressure pump, LS2 timing chain, a 216/220 .525/.525 114 cam, and LS9 springs. Motor is a 2003 model with 202k miles and I was suprised how clean it was:

Everything sounds good, except you need 3.42 or so instead of 4.10s

This build is sick for sure!!!! Nice work man.

What that cam and stall is fine for him, but not me? :lol: I know it's boosted.

Yeah, I know. Thing is, it already had the 4.10s when I got the truck and I'll be running a stock converter for a while, so it'll definitely help the 60ft for now. Future plans are 3.73s and a 3200-3400 stall

That's going to be a wicked beast for sure!!! I love that body style truck, always wanted to get a crew cab dually hauler for my trailer.

Welcome to the site. I was going to tell you that there is lot's of good info here, but looks like you got it covered. Awesome build by the way!

You want to make another set of hot pipes for me? Looks damn good

Love the build, we are relatively in the same boat... Did you open the ring gaps up a bit or keep them stock?

This is awesome

Ring gaps are stock, I never even took the heads off lol

Very nice job! Can you weld on the manifold with a MIG or you need a rod welder and special rod?

Stock shift linkage needs to be shortened about 1"-1.5" and it should work fine

Well I got the beast running last night!!! Got a small water leak by the thermostat and a small leak by the PS pump fitting, otherwise sounds good. But the big problem I ran into is fueling, I had the tune set at 108# injectors, which is what mine are @ 58psi, and I fired it up and it would run for about 2 seconds and die. I finally got it to run long enough to where my wideband heater warmed up and the AFR was peaked out at 17 AFR, so I moved my injector flow rate down to 95# and it idled real good but AFR was still peaked at 17 AFR and if you'd hit the throttle a little it would just want to die. I'm gonna put a fuel pressure gauge on tonight after work and see if mabe the stock FPR is shot... IDK what else it could be?? Ideas??

Well turns out the Bosh 044 in-line pumps dont really work well for gravity feed situations (or so I've been reading) although I took my pre-pump filter out and now it works, kinda for about 15 mins, I can at least drive it around for a little lol. Got a new Walbro 255 with high flow fittings from Glenns Performance on the way,and in the near future I'll have a second one on the way too lol. In the mean time here's a little teaser video lol

First off, the reason the front fender looks that way is because my brother owned the truck before I did and he was planning on repainting it, and he started sanding LOL, and the intake off the turbo, yes I know is very restrictive, but is also temporary. I just put together what I had in the shop LOL

The intake isnt so much restrictive as it is just drawing in hot ass air with the filter being so close to the down pipe and hot parts.

Are you using stock ecm??

Is your boost gauge right? Looks like you weren't building any boost at all ... just wondering.

Yup sure is, but I don't know why it doesn't build any boost revving in neutral... mabe because full exhaust out the back?

The engine needs to be under load to build boost. Revving it in neutral doesn't cause much of a load
