Dyno is not one you would call "happy" by any means, it actually usually tends to let people down... I was let down on my 370 motor numbers and a 370/D1 build was very disappointing.

I know man, I'm pretty bummed about that. I think 535-540/500 would be pretty solid to expect with the 4l60 and 10 bolt under it with the 235s/2" headers.
I'd rather have reliability though!
For how terrible the heads are, I was extremely impressed at the numbers.

That much power through an unlocked auto would be nasty!
I will have Mamo port it since he gets the most power out of it.. And IIRC that is around 500$. There is a lot more things I can put 500$ towards to make more power at the moment. Heads, transmission, nitrous kit, headers will all be bought then I will port the intake following that.
That is where all the power is coming from, definitely not the heads.
