Help me shave off 3 tenths in the 1/4

I don't blame you for not wanting to gut the car. My 64 Sport Fury ran very close to those times. It went 12.12 @110 with a 1.76 60 foot. I feel my car is as fast as it's going to be without some major changes that will compromise the streetability. It seems that's where you're at. Any gear,converter, or cam change will have a drastic effect on the car. Sometimes small changes make a big difference. Disconnect the swaybar. Pop the power steering belt. Un cork the headers if you have them. Change to a light set of wheels just for when you race. A shorter tire will help the gearing.
