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

Re: Max RPM's
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!

Re: Max RPM's
I agree, 2,000 - 2200 is ideal for cruising.

Holy smokes !!! Sorry if I opened a can of worms. I think in the second post Syncro answered my question.

Re: Max RPM's
So how long would one of these "dynamic dampener." last?

Re: Max RPM's
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.
