Re: assembling the Model A engine.
The last engine I overhauled had the main & rod bearings at 0.0015" to 0.002", pistons to cylinder walls at 0.002" to 0.003" and piston pins floating. With new rings fitted, the crankshaft in the short block turned below 50 lbs-ft of torque.
The starter motors always were able to start the rebuilt and overhauled engines in my cars, and these engines have high-compression heads.
