I took my car (66 CHEVYII) out this last weekend to make some licensing passes. I havent made any full passes yet but at half track it ran a couple 6.41 leaving easy off the foot brake with high 1.5 - 1.6 60's. First pass was a 11.39 @ 80 with a 1.44 60'. the last pass was a 10.04 @ 130 backing off around a 1100' because it was leaking water out of the radiator cap (forgot to turn the water pump on) and it was coming into the car..WHAT DOES THE 6.4 CONVERT TO IN THE 1/4? I think when I load up the trans break it should easily do 1.3 60's Next time out I'll let'r rip but that may be a couple more weeks.
