I've got 15 runs with my Trick Flow heads. It's a very mild street/strip car: 68 Charger, 3715 lbs with me and a little over a 1/4 tank of gas.

440 - 030 over
Trick Flow heads shaved 30 thousandths for 10.8:1 compression.
MP Purpleshaft 280 cam
Crane roller rockers, Manton pushrods
Eddy RPM manifold topped with a Holley 850
1 7/8" ceramic headers, 2.5" X pipe with cut outs
Full MSD ignition
3.55 gears, SS springs, 2500 stall converter, Hoosier Quick Time Pro tires

Best 1/4 mile so far: 11.65@117.49 with a 1.66 60'. There's still a little more ET to be had. I'm spinning pretty good off line still.
