Pros & Cons of Insert Bearings

I had a "B" block rebuilt with inserts at Antique Engine Rebuilding in Skokie, IL.. It gets noisey when the engine has been running for awhile. I wonder if anyone else has had the same experience.
 
My "A" engine by Antique Engine runs noticeably quiet early and following a long ride. I use Mobil One 5W30 and change it every 500 miles or maybe three or four times a year. I do not burn any though I do sixty any time I am on a highway or open road. I have the Touring Package, HC head, touring cam, SS valves, etc.

I had one of those engines in my coupe, and it was the best running engine I ever had, and the most powerful.

Use what you want, AER says to use 5w30 or10w30 oil
 
My inserts were done by Schwalms in PA, engine is so quiet you would think it was a Hybrid motor.
 
what is the costs of inserts? if your engine makes noise try upping viscosity. or some lucas can quiet a noisy engine. i have run an old chev small block on 50 weight and it seems to love it 5 years on.
 
5-20 oil is to thin for the engine, that thin of oil is used in modern engines to increase gas mileage use 20-50 in all of my older engines

X2, and what does that thin oil have to do with question :confused: For that matter (oil usage :)) who recommends 5w20 for an antique engine use:eek:

I think Schwalm's specializes in Babbitted Bearings. I believe that was the original Title's Subject though the question did not seem to follow the subject.
