[QUOTE=jpnjim]
Sweet parts combination! That Air Gap was born to sit on a set of ported 304 heads like that, it sounds amazing on the dyno and ought to RIP in a Hornet Wagon! Nicely done John edit, couple questions, did you leave the intake divider intact on this build? did you happen try a pull with an open carb spacer? That 600 Double pumper is probably the perfect match for this engine, just curious if it left any power on the table at the very top (especially if the full divider is intact). Milled a notch in the air gap. Did not try a spacer. Quick fuel mechanical 600 brawler carb was very good out of the box. |

I believe you called it on this one John. On the "304 Ported Heads" thread Dec. 15, you said "I am hoping for 350-375 horsepower with this combination." Looks like you made it.

Well done.
I have a question on the 107 degree, my though's are going to 109 degrees would flatten the torque curve a little but put more HP on the table at a higher RPM. That little stroke engine should rev out to 8000 RPM with ease and not hurt bottom end much at all. You have been in the 0.52x" lift on most of your builds so it looks like you found the sweet spot for a cast head AMC. How are you picking your separation angles? Results are excellent!!!
