I too did a similar rebuild in a 67 Coronet R/T.509/292 purple shaft, 3200 converter,3.91 gears,manual shift auto,TM7 intake,750 Holley dbl pumper,ported iron heads using the mopar performance templates,clutch fan,solid motor mts.Hooker super comp headers 1 3/4 tubes,& S/S springs.

Low 12's thru Walker Race Magnum mufflers that dumped in front of the axle. I ran Milan Dragway all day long on street radials that I couldn't hook.Wish I would have uncorked the pipes, and put on a set of slicks!! yahoooo!! Loved the combo.I am planning on doing another.Fast machine & cheap money. Enjoy! HR20.
