assembling the Model A engine.
Wound this video and found it rather interesting. Especially the part about bearing clearances. I don't know if this method is specific to NEW babbit but found his comment about "everything you thought you knew about building engines...forget it". Thoughts on the interference fit of the crank journals??. https://www.youtube.com/watch?v=anDIASMNmCQ

Re: assembling the Model A engine.
This video series was the subject of a marathon thread last fall when it aired.

If you notice the man from Hagerty says he is not familiar with babbitt. I believe him.

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.
