Just how quick were the 273 Commando's in the Quarter-Mile.

Sneaky Pete,

What I remember from back in 1968.

When the traction was too good, the 273 would 'lag' off-the-line with the
stock Flywheel.

We got a Schieffer Flywheel 'heavy-wheel' which was 38 lbs. We still used a
Weber Clutch-Disc {9 1/4"} with a Borg & Beck Pressure Plate.

It kept the Rev's up when coming off the line.

The STOCK 273 Flywheel from my 65 273 weighed 19 lbs 7.6 oz... I replaced the 273's 9.5 assembly with a factory 340 10.5 clutch/flywheel/bell housing assembly!
And the 10.5 340 flywheel weighed 30lb 3oz... And that's why I previously said I loved the way it now launches!!!

Also I use a Borg & Beck Pressure Plate & and my bullet proof SS Z-Bar (I use to break those early a-body z-bars)

Just for chuckles.. The 273 Bell housing was 28 lbs 8.6 oz...
And the 340's Bell housing was 12 lbs 2.4 oz
So I even saved about 5 lbs... Just saying :cheers:
