Next major upgrade will be head work and probably reground cams.

Welcome BTW.
I'm debating on plenum/IH porting right now. What sort of SOTP difference did you notice when you did that?

Hard to say, I did it over the winter, so it was a long time between drives. I got mine from Lococbob. He did a swap, I bought them from him, and sent him mine when I was done. Plus I had them powder coated. Looks good.

Maybe I'm crazy but I feel like 311 who is low for these cars. I have seen a lot of numbers around the 350 mark for a stock car.

393 WHP is impressive though. I bet it moves rather well and the LS guys probably have a hard time keeping up. Haha

311 was low, picked up what I was missing in the exhaust work. Found a ZL-1 Camaro the other day. Fast car. I'm happy with it, but not happy enough.

Be careful.

Power bug gets you, and 6 figure$ STILL won't get you what you want...

I don't know if I want to go there; it pulls pretty well right now, and I don't have any problem with backfiring, including when I let off.

Now that the water is gone from the tank, it's running and idling smooth as ever, again, (except for that 1.6 - 2.4% TO glitch, which I don't believe is anything wrong (and that Marc says they all have ) ).

Man, have him add the fuel and just ask him to not disable the DFCO. You're lucky to not have the backfire issue; Marc told me mine was running unusually lean on decel anyway, before I made the modifications, so it doesn't surprise me that mine was backfiring like an SOB. Marc feels strongly that you need to add the fuel to get the full benefit. Enhance that Permagrin, Schrade!

At that price point, these are seriously tempting - $509 on ebay right now. Anyone got a pic of Corey Henderson's headers? Wondering how the two compare.

It's my understanding that Corey doesn't build the Jeal header unless it's part of an overall engine build. Just not worth the time and effort as a stand alone product.
