340 Cam Change - Lunati vs. Comp.

So you think the dual plane intake is better for me?? I see ALOT of people using the RPM air gap. I would like the car to be as lethal on the street as I can get with what I want to change. I can't afford to get into aftermarket/alum. heads or anything.

If I do take it to the track, do you think I will run out of carburation at the top end using the 650 DP??

The 10.5 really helps me, and I want to make the most of it.
