1968 '340' Barracuda vs 1968 '383' Road Runner

"Back in the Day" I had a 1969 Roadrunner with a T-Flite and 3.23 gears, and my brother had a 1970 Duster with a T-Flite and 3.23 gears. Both of these cars were totally stock with no aftermarket cams, headers, etc. We raced many times on the street and he would always beat me off the line by at least two car lengths. However I would close that gap and begin to pull away as we got into high gear. This is a real world fact, no offense meant to anyone.
