318 capabilities??

Here was my setup about 15 years ago-74 318 .030 over, other than the pistons and new bearings, stock bottom end. Swirl-port heads, 3-angle valve job, Lunati 292 cam (yeah, I know, I over-cam everything, I just like the sound), Weiand single-plane intake, worked Thermoquad, 904 with a Fairbanks kit, 8 1/4 posi out of a cop car (don't know/remember exactly what gears, something around the high 3s) stuffed into a junker 67 Dart. I lightened the Dart pretty well, stripped pretty much the entire interior except for the dash and one seat. Removed the bumpers and other extraneous stuff, but everything else was all steel. Ran 12.30s-12.40s all day long, drove home, drove to work with it all week. I couldn't afford more than one car on the road back then. I duplicated the same motor for my Volare about 6 years ago. In the heavier car with cruisin' gears it was still good for 13.90s.
