340 Engine Shake

inertia said

The crank can be polished, and many 60 over 340s are running around, I've built a few, including my own 69, I bought new, and wouldn't be numbers matching without 3 sleeves and going 60 over.
Cylinder wall pattern during misc teardowns show no distortion, which I have seen with weak cyl walls .
Ran 12.5 pistons racing at 60 over .
Same pistons trimmed 3 times over the years, about 10.5 now.
Hope it helps, cheers .

Good to know on the crank. I thought it would have to be cut. And I thought .030 was the most you could go. What I'm struggling with is buying another set of pistons and machine work for .060 over. The bearings, no biggie that's cheap.

My mind is instantly going towards a junk yard 5.9, re ring, bearings, upgraded cam and ede aluminum heads. Selling my brand new Edelbrock aluminum heads and my la air gap to fund the ede magnums and intake. And Use my la front accessories with the FItech on top.

In my mind that is the cheapest quickest way to get this thing back on the road. It's not a numbers matching car and far from original.
