3000lb Cuda. 340 .030 STOCK Eddy heads TRW 11:1 pistons stock rods and crank. Eddy AirGap, went 6.71 with a 1.41 60ft pulling the front tires everytime. 5000 stall Turbo Action with 4.88 gears. The AirGap will go WAY faster than 10.90...totally disagree with that. Mine was running around 10.60 in the 1/4.....
