Tom & CNC-dude,

Thanks again for the input, it's all greatly appreciated!

Yes it is low in miles and that's the main reason I'm trying to keep the machining to a minimum if I can help it. I mean I'd love to go the Tom Langdon route and build the "Cadillac" 290 version of this motor. But the reality is I'd like to button this back up with the new rings, hone and cam upgrade with a mild amount of money spent wisely!

And that is why I also mentioned the harmonic balancer. From what I've read a good balancer will make the engine run more smoothly. Is it worth spending the money or reinstalling the stock unit?
