This is Ellis dyno with stock heads, through an auto tranny and 12 bolt.

For comparo, mine is 6 speed/12 bolt, but i dont have any numbers yet.

Im not sure what the other graph on here is, maybe nitrous? anyways...

That's an interesting torque curve. I would have thought it to have been a little more broad, not the continual downward slope. Although, 408 TQ @ 2500 RPM is quite nice also.

Reason I'm asking is that if the 224/230 setup I have now (haven't even gotten the car back yet) doesn't pass emissions, then I may be looking at swapping for a larger cam late this year or so once I register my car in PA with no emissions.

Pesonally, i would ignore the TQ curve because of the auto tranny. I know he has a stall, and would guess that it wasnt locked giving the interesting results seen...just a guess.
