In regard to your question ,a young guy that hangs around my shop and helps me on my race car, built a 66 Dodge Dart 2dr Post Bracket car! This car weighs 3400 # w/him in car has a 416 S/b with a 800, d/p Edelbrock heads flat tappet cam, around 12.0 comp, and no spray! Trans is a 904 w/2.75 first and a 4.30 rear, w/11.5X28.5 Slick, using Cal-Tracs and their springs and shocks! This is an all steel except for a glass hood w/rear open scoop! I think thats about it for specs, the car turns steady times of 10.15-10.20 @ 131.00 mph in average midwest air! At Union Grove Wi. 60 FTs at1.37. It flat as hauls and there is nothing real trick in it. John Lang
