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.

Damn!!! Those TEA TFS 235cc heads will be a very nice touch. It's too bad you can't dyno the car with those TEA TFS heads, ported intake, 2inch headers and CHRIS1313 Ram Air with the same rear end you have now.

I'm hoping so...

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.

I bet you hit 535-540 with the TFS 235s and 2"primaries.
We have similar 408 combinations.

I sure hope so... I looked yours up, very nice! Wish you had some solid track times (traction/etc).

That much power through an unlocked auto would be nasty!

Yes, but not anytime soon.

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.

How does it idle on the 110 LSA?
You going to raise compression when you swap heads?

I wish I had some solid times too. Once it cools off I will see what I can do.

Nice results for the mods used. Looking forward to seeing the new setup. Why are you going 4L80? I'm debating if I should or just stick with this 4L60
