just picked up a 65 2 dr Dart with V8 (273-2 bl) and auto. How do I identify which transmission and rear end are in it? I think it has posi since both rear tires turn and burn. Will a new 340 crate motor hook up to the current motor mounts and tranny and will this tranny and rear end take the increased HP? this is all new to me, so it will be a journey of discovery (and not too expensive I hope). don't want a monster car, but want something that gets a little attention.

thanks

 

Increased HP = expense ! I doubt that drivetrain of yours will hold up to more HP, considering it's original configuration and age.
