Yes, to all, Happy Thanksgiving !
The following is a recap from above:
1. Heavier flywheels
A.some delay in engine over rev
B.Improved bottom end life
C. 100-200 RPM max Rpm reduction w/40# vs. 25-28#
1.Is that enough to cause increased risk of detonation ?
D. May cause increased gear train stress w/ high x
E. May help protect gear train w/ lower x
F. Up to 70# flywheels have reduced harmonics
1. It is said, the Merlin/ Allison uses a 100# flywheel.
2.Harmonics are known to produce heat, which may effect the drive plate.
Is it possible idle quality and dock manners would be improved ?
Is it logical, while some will use full throttle continuous,most will use max. RPM occasionally ?
Is it possible, all things considered, the masses would prefer the heavier flywheel for the sake of durability ? Even if maximum effort performance was effected ?
Is it possible the valve train would benefit from a heavier flywheel ?

I want to thank EVERYONE that has particpated in this thread.
Perhaps,some reader will avoid an otherwise disappointing weak end, boating. Hopefully,I will.
Ben,I feel,the input has been very productive. Your suggestion of two simultaneous weights is very interesting.
Cozzi, you get the Gold Star. Your input and humor is priceless. As Chris suggested, THANK YOU!
My next stop will be at the Drive Plate. As any and all of you may participate, your participation will greatly appreciated!

How about some SpinTron testing? The valve train is what fails most offen in the BBC design. 55 mm cam bore?
What size and weight push rods? Where do we stop? What is going on with the BBC designs in the Northern Dirt Modifieds? Let's get into the real $$$ with some serious testing, we got all winter!
The real BS hasn't even started yet...

I received an irate phone call from Fred Kiekhaefer about me outing his great, great, great grandfather messing with the late Mrs. Trundle.
Sorry, Fred, I thought you knew.
