273 Commando Slugs

A little trivia from about 40 years ago. With the factory formula S 273 10.5 pistons, they had offset pins. The trick was to swap banks, and turn the piston and rod assemblies backwards. In other words, take 1, 3, 5 and 7 and put them in the 2, 4, 6 and 8 holes, but notch to the rear, not the front. It was suppose to be worth more horsepower and up to 1000 more rpm's, but you might hear piston slap until the motor warmed up, but didn't hurt any parts.

I did this to a couple of motors, and although I didn't quite get 1000 more revs, it definitely up'd the power and never had a problem. The TRW forged replacement pistons (I think they were L2222F) had a centered wrist pink, so the above wouldn't make any difference.

Like I said, just trivia I remembered when I read your post.
