June 10, 2010:

An update to modifications made to my 225, 67 Dart rag top:
Oversized ENDG valves, ported, gasket matched, and shaved 0.075â€￾ calculated 9.5:1 compression peanut head.
Clifford intake & shorty headers, Holley 390 4V carburetor.
Dual exhaust.
Bored over 0.030â€￾ block.
Unknown hot cam that loves 3000 to 5000 rpm.
Orange box, blaster II coil.
904 driven by a 2600 (on paper) stall converter. (Seams to lock up @2200)
3.55:1 8 ¾â€￾ Suregrip, D70/14 T/A’s.

Haven’t weighed the car, but is most likely on the heavy side north of 3100 pounds (+ 220# for me) because of; HD suspension, anti sway bar, sub frame connectors, 8 3/4â€￾ rear, and sound deadening on floor. Nor has it seen a dyno, so I don’t know what the torque, and power curves look like.
