Our project is to convert a 1976 Dodge Ram former military truck that has a slant 6 to a 360 that came from a 78 Dodge Prospector truck. The slant-6 is a 3-spd on the tree, and the 360 has an automatic transmission.

We'd like to make it into a 360, 3-spd on the tree so minimal changes to the pedals/steering column are done.

Question is, what flywheel should we use if it is the original 360 from the Prospector truck? I.e. is the 360 externally balanced and is their a specific flywheel we need to use to make this work? Can we use a small block bellhousing that will work with the existing slant-6 3spd transmission.

thanks!
