Your wasting your time trying to reason with him. He likes to argue and I think in his mind he is never wrong. Over the last four years on the Barn I have learned to ignore a number of members comments.

At my age it is not worth the time or energy.

Enjoy.

Well I don't know about that as I definitely listened to your advice on different topics when you were here visiting. Never too old to learn from those who share similar experiences on a, -or the subject!! As to our dialog here now, it definitely seems we are hi-jacking this person's thread, so we should probably get back to providing on-topic interaction!!

Well I definitely hate you feel this way. I guess I am guilty of that in some ways although that is never my intent.

I am not comfortable with pushing an old engine even if it is rebuilt. I have a stock 1930 engine, 5.5 head, 3.78 rear end, Borg/Warner T5 transmission, tachometer, and a spot-on speedometer/odometer. At 55 MPH in 5th gear the car rides very comfortably at 2200 RPM. I have found (4 years with this engine) the RPM comfort range in 3rd, 4th, and 5th gears is 1800-2200 RPM. A few times I've had it over 2600 RPM and to me it sounds like it is starting to scream. Treat the engine like a kind old lady!

I agree, 2,000 - 2200 is ideal for cruising.

Probably 50% of the questions on this board are answered correctly within the first three replies, following by 20 posts of kibitzing.

So how long would one of these "dynamic dampener." last?

The BHJ Dynamics white paper, see link in earlier post, says "Properly designed, it is effective, reliable, and long-lived." The life depends on whether you are constantly at the resonate frequency, about 2,600 rpm in a Model A engine. The dampener should last at least 100,000 miles in normal use, but this is just a guess. The manufactures of OEM dampeners do an endurance test that simulates 100,000 miles.
