Whats Next for my truck???

[pl4yboy]

So currently I have a single in tank walbro 255lph fuel pump and 44# injectors. For sure I am gonna pick up some 60# injectors. Im running the stock return style fuel system with stock lines through a vette filter/regulator in the engine bay, if that makes any difference? Ive heard mixed reviews on whether or not my single 255lph will support the power I am gonna be making. You guys think I may need a dual walbro 255 set-up?

Plan is...

383ci 9.0-9.5:1 CR
Flat top Pistons (not going to tear into the bottom end)
317 Heads (maybe Patriot CNC)
Pat G spec cam (for turbo)
90mm intake w/ stock returnless style fuel rails
Trick Turbos Stage 4 kit (76mm Turbo) (not sure on PSI yet)

Thoughts???

Thanks,
Ty

It would probably be smart to go ahead and do it. For as little time and effort it takes, it would be worth it.

might as well...youll always want more...just a safety net

Ok. Dual walbros it is. Anyone have experience with the Lonnies Perf unit? Home-made units? just looking for the best route to do it.

Also compiled a list of parts for my Pre-turbo build:

Patriot CNC 6.0 Heads
or
Basic 317 heads
ARP Head Bolts
Pat G Spec Cam
Yella Terra 1.7 Rockers
Hardened Pushrods (not sure what length to use with the yella terras?)
Gaskets
60# Injectors
Dual Walbro Set-up

Anything I am missing?

Thanks Again!
Ty

How much PSI can I push on my motor if I had a 9.5:1 CR?

Well its been a tough couple months money wise. Had to sell off all my turbo stuff. Blew the sunshell out of my tranny. But things are looking up, I decided to keep the truck N/A for a while before diving into FI just yet. Just ordered an FLT level 5 4L65E & Yank 3000 stall verter and some ARH 1 7/8" LTs. Going to order a Pat G spec cam for it later this month (226/230 ish). Trying to hit 400ish whp/wtq. Think its possible?

383ci 10.5:1 CR
Pat G cam (226/230?)
243 heads
TBSS 90mm intake
ARH 1 7/8" headers

Very possible. Good luck.

I'm hoping 360ish is obtainable with my setup so you should be able to hit 400 with that no problemmo.

Got final cam specs 226/230 112lsa. Should sound pretty good too. I'm stoked to get this thing running for summer!

man, your numbers are way low for a 383. pat g spec'd me a 226/230 on a 111 lsa for my 5.3, but ill prolly go a little bigger. Im trying for close to 400rwhp with h/c/i. If it was me, I would go with a bigger cam but my truck is lighter i guess. I dont see why you should have any problem what so ever making 400 rwhp with a 383. Just make sure you get it right, and Im sure you will be satisfied. If you make 400 after the build and its still not enough, spray that bad boy, Iron block, forged pistons and high compression sounds perfect for a 200 shot!!
