Big Valve X Heads on Low Comp 72 340

Back in the day (1978), I put some cheap Blackjack headers in my otherwise stock low-compression daily driver 73 Duster 340, 3.21 open rear, and picked up over half a second in the quarter (15.0s to 14.40s). Would have done even better, but the headers gave me so much more low end that now I had a traction problem. Headers also raised my shift point from 5200 rpm to 5800 rpm. Except for the headers, the exhaust system was factory stock.

I traded that Duster for a 1982 Charger 2.2 in November of 81. My first new car. Dumbest thing I ever did. . . .
