Like a number of you I made my first pass down a drag strip with a 390 Ford. I purchased a 1967 390 GT Mustang fastback on graduation day in 1974 and took it to Irwindale raceway on Wednesday grudge night. It was a little tired 70k mile 390 C6 with 3.00 gears. Ran 15.30 on first pass with some tire spin. Freshened motor and added headers and it went 14.70 still spinning. Pulled the 3.00 gears and installed 4.11 and it went 13.90 with lots of spinning. Didn’t know enough to switch to a locker or spool back then but as a 18yr old it was more fun driving around town and being able to smoke a tire most of the way down the block.
