Thanks for the replies everyone! Did I look like I was missing anything in my parts list?

 

List looks good, heard too many horror stories about fast intake, aside from cost, with fuel rails sensors etc not fitting properly....

 

Ok so I talked to Texas Speed and told them about my goals and they recommended the following. Please let me know what y'all think or if y'all have any other input.

Cam: Texas Speed Torquer V4 231/234 .629/.615 111 lsa
Heads: PRC As-Cast 225cc LS1/LS2 Cathedral Heads with 62cc Chambers
Valve Springs:- PRC .650" Lift Dual Valvesprings with Titanium Retainers
Lifters: LS7 Style Lifters
Timing Chain: LS2 Timing Chain
Oil Pump: TSP Ported Oil Pump
Headers: TSP 1 7/8" Stainless Long Tube Headers

Still need to figure out:

-Injectors
-Fuel Pump
-Intake
-Stall (I have a stall right now but its only a 2100 and I don't think that will be enough)

So with this heads and cam setup is 400 rwhp achievable? Thanks for your input!

 

Stock heads will get to you to 400 horsepower, so you could save a big chunk on money there.

Marine 8.1 injectors are like 42lbs I think, those should be plenty of injector. A walbro 255 fuel pump will be good.

NNBS intake manifold like we have talked about before in this thread.

 

Ok thanks for your response! If the stock heads will get me over the 400 rwhp goal thats great but if I can make more, I'm willing to. Also something I forgot to say the truck is a 2500 on 33s so drivetrain loss will be greater.

 

I wouldnt get your hopes up too much on the 400 rwhp. Im the same boat as you, 33s on a 2500 4wd. When I had my old turbo at 7 psi it only put down 380 rwhp. At the crank yeah 400 no problem. Like right now I put down 460 with a bigger turbo and 11 psi but guys with my same setup in a 2wd make 500-550 all the time. Dont get hung up on numbers thats what I had to learn
