But you got power i hope. Mine need a tanker in tow with no power. 13 MPG and wont pull . I've got a 78 Dodge Maxi Custom van with a 60 over bore 400. Comp. cam a little head work, performer intake with 4 barrel carb, and a few other little mods. It gets 13 MPG highway and runs and pull like the dikins. I've been thinking about putting the Gearhead mod on the 747 trans to get overdrive. Anyone have any suggestions on that.
