Lol, the SRT6 is as broken in as it will get, trust me. If it is a "hack job", I see I am in the wrong Forum. I'll just take my 685 whp "un streetable" LS1 Z, 12.7@109 "beater" crossfire and my plans for what is to come and keep to myself. Enjoy. When you say that "no one has done it"- they have, they just don't come here and talk about it. Now I know why. Lol, when people start preferring a roots over a centrifigul and talking about a wide band to monitor the AF like it is a huge ordeal, I know I am in the wrong place. I have 24-7 access to a 4 wheel dyno (family owned shop), full CNC setup, all the tooling, welders, benders, etc. you can imagine to fabricate anything you want and have been doing this for over 14 years now, so please don't talk like this is a waste. Tuning is easy, fabricating is fun and when it is all done, a bolt on kit with intercooler and mapping would have been a possibility. I know where I am wasting my time however.

PS- Yes, with thicker headgaskets and ~9:1 the 3.2 will handle 14-16. Know of a couple right now. Can't say it will give you long term reliability that a stock setup would, heck you're in the wrong game if that is a concern anyway, but I have seen over 400 whp and several 1/4 mile passes on a couple MB's with turbos and such. Like I said, been around the game a while...
