KevinAZ:
ok. So u've got a good transmission, IIRC Craig overhauled the engine so u have one the best engines AND with Olds pump. U ought to get 100K miles of trouble free operation at least. Mite need a little carb work every 40K miles or points or other minor regular maintenace but overall it looks like the optimal set up.

It will be interesting to see what kind of gas mileage it runs on open hiway at 60-80 mph on long hauls.

What is the rear axle ratio???
