***273 Commando pistons and '302 heads???***

I did this swap almost 10 years ago for a friend; he wanted to do some up grades to his car, I helped.

With a .030 cut on the heads, measured compression ratio came in at 10.48 to one, he stayed with 1.78, 1.5 valves, swapped in a Crane hydraulic cam, an H260, Spitfire headers, Holley Street Dominator intake. A nice wake up for his 65 Dart GT.
