Anyone know what class the car would go into, and the record for said class?
Here is my guess, B/FALT or /GALT, your 427 makes it a B motor, it is an altered coupe due to your ducted air through the removed headlights. F if you run alcohol, or G if you do gas. Records in the07 book, F-235.6 and G-238.88, could be higher now. Luckily you didn't mention a blower....
150 club would be a good, fun place to start your addiction...
