I ran a '65 Dart all summer with a very mild 416 on pump gas. Went 11.70 in the 1/4 but 7.37 in the 1/8th. Don't choke it off with crappy heads like we did. Ours were stock unported 360 heads with chevy valves, and it just lays down after the 1/8th mile. Changing them out for next year. Car was 9.5:1 compression on pump fully tagged and street driven. We run slicks for the track, but it 60ft hard enough it needs them. Car is just nasty fast till the 1/8th and should run low 11's early next season. The 416 is a torque monster that doesn't need a ton of gear to go really well.
