Go with a walbro400 and either 60s or 80lb injectors.

I would do a dual spring instead of a beehive. You will need to wait until you get everything back together and measure for your pushrod length. Use LS9 head gaskets, LS7 lifters, and the rocker trunion upgrade is fine instead of replacing the whole rocker.

 

+1 on the triple 12, assuming your truck is your avatar youre not a street queen like mine. Its not as choppy as I like but its great for everything else. Stock48 also hooked my up with valve springs too. I did LS7 lifters like mentioned, hardened pushrods, and a summit ls2 chain just for insurance. The port and polish isnt really necessary honestly for a boost build, that money could be more well spent on meth imo. And I also run a walbro 400 with 80 lb injectors and my tuner said im no where near maxed out which was what I wanted. Only thing is you need an adjustable regulator for a 400 because it over powers the factory one. But since you have a return line already that wont be hard. Wouldnt be a bad idea to read through my build thread since it sounds like youre going down a similar road to me.

 

Thanks for the reply and useful information! I contacted my tuner and am waiting for a reply also. I will definitely take a look at your build

 

Tell your tuner to make the cam chop

 

Yeah I head about using the tune to make a choppy idle for the first time the other day this is a real thing?

 

You can make a stock cam sound choppy....you can also tame a larger cam or make it violent...

My old setup you could tell i had a cam and was a JFR 218 but when i first put it together i tamed it...my truck also went thru 2 large mufflers


I made a ls6 cam chop hard back in day on a turbo car as owner wanted sound
