12 valve performance progression

[djwhiterob]

after getting to know my truck I've bought a few parts for. I believe most are on my sig but I have 90 hp injectors some sort of delivery valves with stock turbo. Pump mods include the rack travel mods with a 6 ate and afc slid all the way forward intake and exhaust dd clutch five speed with 4.10 rear end. The next break I get the head studs 4k gsk and vve springs are going in. I almost pulled the trigger on a super b special and some 5x.014 injectors. Where do you guys think I am now and where do you think I should go. Looking for 600 horse on a dd

What's your budget? What year truck? 600rwhp might take a bit of work.

5x14's and the Super B Special was a great DD setup. Not sure what I was at for power. Swapping the 64mm for GTX42 and GT37 twins, I did 520 on a no load dyno.

5x.014 some moderately cut delivery valves and I'm sitting on 600 with some real simple mods. That's all that is different from my signature is the injectors and delivery valves, oh and 5k governor springs
