Which air gap manifold?

Thanks guys, looks like it'll be worth the change.
Other rebuilds this year include putting a Suregrip in the rear and using MT Darg Radials at the strip.
Current et is14.2 (98mph)due to the wheels spinning so much off the line. Hoping to bust into the 13s (mid 13s?) next year once all the above changes are in place.:thumbrig:

FWIW, I am running the Profesional Products Crosswind intake with a Cop XE268H cam. The Crosswind is very similar in design to the RPM AirGap but has slightly smaller ports. I am also running magnum heads, a 670 Holley Street Avenger carb and 3.55 gears with an A833OD tranny. My best 1/4 mile is 13.7 @ 102 mph with a misreable 2.2 60' time and that was with a 600 cfm carb (no numbers on the 670 but the butt dyno tells me the top end is stronger). I figure if I sort out the lack of traction and wheel hop off the line its an easy low 13 car.
