AI heads and baby cam dyno AI 200cc heads and 22X 23X 56X 56X on 110 LSA, RKSport 1 3/4 mid length headers, Hooker cat back, AS&M 54mm TB, racetronix 32lb injectors.
I had about 7 degrees of knock retard and it was a little rich in the upper RPMs. I think with a little work on the tune and a cut-out I'll be pushing 430.
The guys running the dyno said it was reading low for some reason. They had one car on today that was on yesterday and it made 50HP more yesterday. There was also a guy that had his on SpeedIncs in Chicago dyno recently and he made 35 less on this one.

Those RK sport headers are messing up the low and mid range torque. Not so much the peak HP.
Definitive proof LT's are better than Mid-tubes
Red = previous setup with RK sport mid-tube headers & 30# injectors
Blue = current setp with LPP long tube headers & 37# injectors
397RWHP is about right for that setup IMHO through the 10 bolt.
Aint no way in Hell you can expect 430RWHP out of that cam. Forget about that.
The torque on the OP's graph definitely carried itself well at the end.

I don't see 410-420rwhp being a problem with a cutout and getting the tune fixed.

Its just that those cam specs, in general are not really expected to provide 430RWHP. Sure those numbers are easy with a larger cam. Thats just based on what I have learned over the years.

I've been thinking about long tubes for a while, but my car rides pretty low and I don't need any more dragging exhaust than I have now.
A rear end is next on the list, I hurt the rear end the first time I shifted hard over 6000 RPMs. I'm going to be ordering a Midwest with 4:11s in the next couple days. I bought some used ET streets and will be heading to the track as soon as I get the rear end in.
I will have a cut-out and the tune tweaked before it sees the track. I'm not expecting anything great on the track as my car is very heavy, the whole interior is lined with an aircraft equivalent of Dynamat, and with the C5 brakes I don't have an option for lighter front wheels and tires.

The MidWest fabbed 9" is nice, I installed on into my buddy's LS1 Fbody.
