Help evaluating this car...69 DART

I believe the only slant A727 came in the pickups and vans. Pass cars had the A904.

People use the A727 in high HP builds all the time. I am a 4 speed guy, maybe somebody else can chime in as to how much HP they can handle.

Mopar made an O/D version of the A727, and A904 that could give you power and an overdrive gear.
