Holy hell!!! This is very impressive. Funny you guys went from a 5psi pull to "**** it, lets go 15". Love it

Post up another engine pic please

 

awesome build and numbers. Keep cranking it up!

I was curious to see what a 450 pump would do. Might be easier to drop in twin 340L pumps. They are pretty compact and would probably fit in the stock pump housing.

 

Thanks everyone for the replies Im thinking about the fuel system now. Want to keep the stock system working so I want have to worry about the engine light. Going for the twin 450's just tee into the one in the stock bucket. And regulate the second pump to the 58lb that what the stock FPCM control command the other pump.

 

that's awesome you could take 1 450 to over 900 rwhp. I can't get 2 450s much over 800 rwhp on a stock fuel system.

 

GMCTrk that crazy. Post up your fuel system.

 

Guys I been driving around enjoy the beast for 600 miles and Im loving it. Even took the beast to the grocery store...Also I started the fuel upgrade plan and parts list.

 

Guys I got the air filter installed and started to relocate the battery. Under the hood in the old battery location I shorten the battery box and install the two battery firewall pass thu. Going to remove the bed and start the install of the battery box and cables. Plus installing the new fuel system. I have a few pics of the work done so far.
