Right on! Looks like a really nice street combination.

I'm really pleased with the torque, especially the peak torque rpm. Not too hard to get 650-700 hp out of these big windsors, but to make 560+ lbft at 4200 rpm and match it up with almost 540 hp does make me giggle a little. Smidge over 10:1 for that California swill, sounds really nice, and makes good power.

Wow, that is a nice motor.
How low in the rpm range did the dyno measure? I'd be curious to know what the torque was around 3000.

For that size engine, I'd use the Air Gap. It will have more average power and torque.

How much do you want to spend on it? Porting a dual plane can get into some bucks.

Are you looking for hero numbers or for something that's best in the rpm range that you'll be running?

A Performer RPM or Air Gap will out run a Victor up until about 6200-6300 rpm.
