That project should keep you warm for the Winter.

Speed in a CMP is a bit of a problem...... designed like a brick it was not meant to go fast but to be overloaded, abused and survive rough roads.

Normal confortable speed is 35 to 45 on good paved roads with a 216.

The smaller CMPs had sixteen inch tires and could afford to use a higher gear... in the larger trucks like the CGT.... to make up for waht was lost on the 20 inch tires they lowered the axle gear to almost match the other vehicles speed.

A 261 will give you about 50% improvement on HP and torque and according to Phil Waterman will cruise at 50 mph and hold it's speed on mild hills.

I would not go through the trouble of changing the axle gear clusters unless you intend to commute on the 401.

Keep in mind that with more speed you will need more brakes.... your overall weight will not change...... lots of mass to stop in a panic. CMP brakes are good if properly set up and adjusted regularly..... but they are 1937-39 technology...... a brake booster can be installed.... you might even find a NOS one....... but the basic mechanics of the brakes system will not change and the stopping maybe easier on your leg but not much shorter distances.

OH.... don't forget when you install the 261 you will need to replace the stock water pump with an A-dapter plate and a rebuilt 216 water pump. Otherwise you fan will be to low on the center of the rad and the fan will be touching the radiator. Easy job to do before the engine is installed.

Looking forward to seeing pictures of your truck.

Good luck
