I found an article about it in old SOSS magazines..college kids set up an A with 18 to 1 compression and a scroll type fuel injection pump and nozzles as part of an engineering program. As I recall from reading the article the engine performed well. The square inch contact area of A main bearings exceeds a chevrolet 6 cylinder main bearing contact area.I understand why builders push inserts,they are fool proof,line bore and install,no risky tinning and peening,no temperature issues,perfect for business,reduce the comebacks.But the stories that babbit doesnt hold up or isn't as robust as inserts is just plain wrong.On a low rpm engine there is even an argument between counter balancing and dynamically balanced cranks as well.A decent harmonic balancer with a dynamic crank and a balanced rotating group should yield effective results at a fraction of the counterbalance costs.
