Show me your 273-powered race cars

not knowing your cam specs ,the 1966 D dart used thorley headers in most cases, a few had factory cast iron headers, cam was a solid .513 I believe 4 speed, 8 3/4 rear with 4.80 gear. I passed on an original 66 D dart for 100 bucks in the early 80s .50 made. old man owned it and worked at a convenience store and asked if I wanted to buy it for 100 bux. he kept saying this is not a dodge dart ,this is special, its a DODGE -D dart, I was a young buck and didnt know any better so I would tell him to let me test drive it just to row thru the console 4 speed. wouldnt do much over 100mph but it got there fast. my day is now ruined,lol
