It's basically a stock 06 5.7 with the SRT Max Plus cam and a set of headers. I do love the exhaust setup though. It's a really nice blend of good tone without being annoyingly loud. In theory it might make 400 at the crank, but I haven't had it dyno'd since I've done my latest work on the tune. Only dyno run I ever had on it was one of my original tunes when I was still learning and it only made 270 at the tires. I was really nervous about timing though because I didn't have my knock sensors on it yet and I know the stock pistons can be a little fragile if you aren't careful. They can take a fair amount of power, just not a lot of knock. Hoping I'm closer to that 400 number now, though ironically it probably idles smoother than those clips. This may have still been on my carb setup, but I really can't remember when I did the cam vs the fuel injection.
