As for the NHRA specs for the 69 330 horsepower 383, is that the B body 330 horse engine or the A body 330 horse engine? I don't think they are the same, and the B gets that rating with the smaller cam, while the A gets it with the bigger cam. At least that's what I've always understood. It's not inconceivable that I've always been wrong.



it does reference A body engine different than b body for 68 , have to check 69 .

My dart is a late build car, end of May 69, I don't think it had the original exhaust so I don't know about the headpipes, just that it had the tips and they were the tiny ones. I now have a mandrel bent 2.5" manifolds to tips using the accurate SS 2.5" tips .
