My 1950 ford f-4 pick-up is stock as a rock w/ original 100 HP. FLATHEAD V-8 - 3 speed man. trans. and high ratio rear end . My problem is ,I really want to keep this truck as traditional as possible but I also want to use it to pull a (2) car wedge car hauler w/2- 32' highboy roadsters . I'm looking for suggestions as to how much performance i can build into the original power plant vs. transplanting a modern crate engine/ trans.
