I am in the process of building an A engine. Quote from shop used for inserts on prior 3 engines was $800 for align boring mains plus inserts and thrustwashers. Quote from popular So Ca babbit shop was $625 for rods and mains. Mains only $525. Babbit in this engine looks okay so will refit rods and mains with shims. No longer "brainwashed" about needing inserts. Those that feel the need for inserts go right ahead. I started messing with 4 cylinder engines in the late 40's and they seemed to last just fine with babbit unless they were, truck and/or automobile, run too fast too long. I feel this problem is not quite as critical with the use of overdrives.
