I've got all 3 intakes and I need help figuring out which one I should run. I've been running the Air-Gap but I'm wanting to pick up the ETs some. The M1 and Victor 340 are untouched single planes. The best it's ran so far is 11.35 at 118mph with 1.57 60 foot times. Here are the car and drive train specs:

1968 Fastback Barracuda
318 stroker (390cid)
K1 4" crank
Eagle Rods
Ross flat top pistons
Edelbrock heads (OOTB)
Air-gap dual plane
BG 750 silver claw
Comp solid cam (.540/.555 252/262 @.050 106 lobe sep)
TTI headers
727
Dynamic 9.5” converter
3.91 gears in a 8 ¾ sure grip
Cal-tracs, mono leaf, Rancho 9way shocks
Cal-tracs 90/10 front shocks
Carter mechanical fuel pump
full exhaust with Dynomax turbos
full interior
3,400lbs race weight
ran 11.35 at 118mph shifting at 5,700rpm

This winter I’m:
putting a roll bar in
pulling out the stock tank and going to a 5 gal fuel cell
Aeromotive 2000 fuel pump
moving the battery to the trunk
moving to a spool
4.30 gears
M1 or Victor 340 intake
Holley 950 Alcohol carb
Going to Alcohol

Hope to be running 10.90s next year.

Any other info needed, just let me know.
