[Healeys] Lightweight Flywheel

I have a lightened flywheel in my BN1 (26 pounds as opposed to 42) and I've used it for over 13 years with no known ill effects. The engine has been out for an unrelated failure and the crank checked out crack free. I use the car for highway cruising and around town and I don't spend much time above about 3200 RPM. I have Mike Lempert's 3.54:1 gears (hypoid final drive) and the 28% overdrive which gives an 80 MPH cruise at around that RPM. No land speed records, but no speeding tickets either...

BN1 #554

Has anyone used a lightweight flywheel on their 100 BN1? I plan on going with a complete Le Mans kit and a lightweight flywheel and the car will be for street use. If you have, what are your thoughts on it? Thanks.

I encourage as many people as possible to "M" up their 100's.
Makes original cars that much more valuable.

My understanding is that the 'kits' installed by dealers varied; the
complete one--the one done at the Healey shop--includes higher
compression pistons, a more aggressive cam, some suspension tweaks
(stiffer shocks, maybe a larger anti-sway bar), a different distributor
and, of course, the louvred bonnet.

Someone wrote up a list of mods that could be done--even better cam
profile, for example--that could be done to a 'stock' BN1/2 to achieve
performance superior to a M, while keeping the original 'flavor' of the car.
