Hi Phil

when I had my 261 rebuilt I read and it was confirmed by the engine shop manager that Chev 6 are seldom "balanced" as they are deemed "inherintly" balanced by the very design of the engine crank..... which apparently is not so for a V8.

In any event, for an extra $300 they did balance the 261 ... the focus was apparently getting each piston assembly....new piston, rings, rods, wrist pin, etc. within on gram of one another......

Doubt I will ever spin the engine fast enough to take full advantage of the process .... just hoping that it would make it smoother running even at lower speed.
