Find an old mid 70's ford truck or car and rob a 400 M motor out of there and stuff it in there. They are cheap and plentiful and make about 200 hp stock. If you put on aluminum intake, rv cam, and headers they are quite strong. They have the same bellhousing pattern as the 429-460 motors. 460's are kind of useless too. They can be had by the thousands for very little cash but they are pretty lazy. You can make them run with aftermarket aluminum heads.
Problem with the 400M in a medium truck is that I don't believe there is a 400M flywheel that will accept a medium truck size clutch. Pickups never used a clutch larger than 11-12 inch, while most medium trucks run larger clutches. None of the 361/391 or 370/429 flywheels will fit or balance a 400M.
Big problem with that 370 is the low compression in large part is killing fuel efficiency. Problem is though that unless it needs a rebuild anyway,
you have very little chance of recovering the rebuild with high compression in fuel savings. |
