We have fitted a E 6 - 350 / 2 valve Econodyne motor into a B model. The motor came out of a 1982 - R686 which had the intercooler in front of the radiator and one air cleaner. We have converted the intercooler to an intercooler over the top of the engine as in our pictures. We have fitted 2 Donaldson dry air cleaners. We are told that the intercooler over the engine cannot be fitted to a 4 valve motor.

Apology re my comment I forgot to say that the E 7 - 400 hp / 4 valve motor is not set up to take the intercooler on top of engine, we wanted to fit an E 7 / 400 hp motor but were told by a Mack company man it can't be done - is this true,
we had a good working E 6 / 350 so we used it
