This is my setup. Car made 440/387 today in 94* humid weather. I've had several people say it has head work, but the runners look stock to me, still have the factory casting look. Is this a higher than normal number for the setup? It was not made just to see a number so no toying with the tune or anything like that. Timing was at 28*. AFR was right at 12.

I guess I should've worded that better. The dyno is on par with other cars. I think mine is high too but I looked into the runners on intake and exhaust and compared them to a friends stock heads that just came off his car and they look stock. Idk if they're milled or anything, but I don't think that would still put it where it is. The car made 417/379 with ls6 intake, stock throttle body, slp lid, stock maf, stock rockers, and 1 3/4 headers.

I would be curious to see what it would make with a PRC 2.5 LS6 head on it but I'm gonna build a 408 for it and wait to choose heads then. I've got a nitrous kit on it just getting the stock motor where I want it and I've got some chassis/lightening to do now. It's a full weight 99 SS leather int and all. The only reason it was put on a dyno before the work that I did was to prove the gain I would get bc I had a couple ppl telling me it wouldn't pick up more than 10hp going from the ls6 intake and 1 3/4 headers. I'm not really all that concerned abt the number, just curious with the higher number considering the mods
