TQ on LD340 or Air Gap

Good deal. Thats the way i was leaning for a bit was trying the Air Gap just to see if there was any improvement. owrse case the LD would go back on...

The motor is a 69' 340
Steel crank and rods, forged pistons (.030 over due to corrosion on the cylinder walls)
4-speed w/ 3.23s
Lunati Voodoo 60403 was the number at the time, heads cleaned up along with intake and header port matching.

The car ran mid 13's with a 2.5 sec 60' time at 103mph so once i improve my launch im hoping for high 12's.
