Chrysler says real power for stock 4bbl 440 is between 270-330hp. this probably includes 8:1 engines. the 440 in my 69 r/t is 9.3:1 compression (kb184 pistons and 906 heads with some pocket porting), 272-.455 cam, stock exhaust manifolds, stock avs and intake, and stock 2 1/4" mufflers. I estimate 325hp; definitely no barn burner.


I do have another article of a chassis dyno test of a '70 6pak super bee if you guys want to know what they really were.
