Well I finally got my 46 216 running right. I found a second fuel filter directly under the gas tank and it was really clogged. I also got me a donor intake and exhaust manifold set that has a working heat control unit and now I want to clean it up before installing. I know some use the Calyx to renew the finish but has anyone tried the Slip-Plate spray product? It sounds better than paint or Calyx. I am really questioning my motor, compression is 110 on all cylinders, and starting and running OK now. The stamping on the passenger side near the starter is only T-41 ,it makes me wonder if this is a 41 motor. This truck is Canadian and researching is difficult. it had an older 3 speed trans with a smaller bolt pattern, I put in a proper date coded 3 speed in it now. It had 2 sets of holes for the tranny bolt patterns. anyone had any experiences with these Canadian trucks? I don't know if this is how things were built back then, or if in the last 70 years someone swapped the motor and tranny or what. Also I read the ring and pinion swap kit may not work on Canadian trucks. Where can I get info?
