That's absolutely awesome. That gives me high hopes for my new engine. I'm guessing you are running a 4.125 stroke and a 4.03 bore?
I'm building a 408 dry sump, solid roller engine for my Formula. My SCR is going to be right around 11.5:1. I'm using the dry sump system off of an LS7 including the crank. The heads I'm using are ported 806 heads. I don't think they'll flow any where near your ET 255s. I'd like to use a sheet metal, but I'll be using a super vic with a 105mm tb. The headers will be the same. I hope it'll make 550, but you're giving me high hopes.

great #'s I see in thge list of mods you have a 4" mufflex catback I assume these #'s were made through it. The reason I ask is because I have a 4" mufflex with a spintech muffler And I havent put it on the car because I was scared I would lose to much power. With your #'s that doesnt seem like the case and I really want to quiet my car down on the street. Does your mufflex system have the spintech muffler? Love to here a vid of it running.

Bump, still would like to know if the #,s were through the mufflex and which system you have.

nice numbers, my motor is very similar, I make 590 rwhp with a stock ported LS7 intake and 12.1:1 cr IIRC. I run on 110 though becuase the 400 hit is gonna go on it real soon.
