[Healeys] Lightweight Flywheel

[glemon at neb.rr.com]

I had my flywheel lightened by a local machine shop.  It was done in conjunction with an engine rebuild to M spec, so it was hard to evaluate the effect on performance.  However I can say there were no I'll effects as far as idle or clutch/take off operation with the lightened flywheel.

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...
