Over the years, I've converted two vehicles "back" to heavier flywheels, because the light ones were too light for the application.

 

One of them was a hi-po Corvair 140hp [four carb stock, this one was higher comp. and converted to Holley] engine with reverse camshaft & dist drive, installed in a '60s Porsche 912, a not-unusual retrofit in those days, owing to the cost of rebuilding the 4 cyl 912 engine after it blew up -- also not uncommon. With the reversed bits, and a trans adapter, the Corvair ran "backwards" to match the Porsche drivetrain. Took me months to get it sorted out after the last five Covair "experts" had had their way with it.

 

As I got it, it was nearly impossible to drive, with the combination of too much carb, too much compression, and almost no flywheel. I put the two-carb heads on it (lowering the compression), knocked it back to a single two barrel, and had a heavy flywheel made from scratch. The car was quite liveable then, and the Doctor who owned it was very happy with the transformation.

 

Be careful what you wish for, you may get it.
