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

Winter 1968/1969

After running the 273/235 HP for nearly 2-Years, and getting down to the 14.30's
my Father finally yanked the Engine out of my Mother's 67' Barracuda.

The block was bored .040" over, and we got a set of Mopar 10.5-1 Pistons. Yes, they
were heavy-slugs.

The block was 'decked' to specs, and the deck surface was 'O-Ringed' to insure a
proper seal. {those damn 4-Bolt per Cylinder Head Bolts}.

No balancing in those early days. And the Crankshaft was 'polished only'. And the
Connecting-Rods were not even reconditioned or checked for out-of-roundness.
We even kept the same original Rod-Bolts.

That was 'norm' back then.

We did get a set of 'Premium' Piston Rings, which were a set of 'Perfect Circle'
Chrome-Moly {#5878} units.

And we did use TRW 'Clevite 77' Bearings. But that was it, along with a High-Volume
Oil-Pump.

No Deep Oil-Pan either. Just a 'windage-tray' off of the Mopar 340.
