Things you did/upgraded that surprised you how helpful they were

1. Changing from drum brakes to front disc's and Large bolt pattern (15s) all the way around.

2. All new wiring, no more intermittent issues.

Oops, this is the racers forum.:steering:
Members here just steered me to Summit's 15" SBP wheels for my 70 Swinger 340. There are no 14' performance tires. With these, I'll get a bit more rake(always cool) and keep my SBP rear end and axles. The amount of knowledge on this site is amazing. Thanks to all my Mopar Brothers and Sisters.
