They were good simple trucks. The mack engine has a lot of torque at low rpms thus the 5 speed is all it needs. The rears are automatic locking in away. Probably a 237 engine good in there Day but will be no speed demand by today's standard. Look at the trunion down where the tube crosses for the camelback suspension tends to crack out on the inside.
