Here is the engine were building for our 72

[grumpy]

Just got news theres more metal shavings in the oil then I would like.
Not jumping to conclusions but if there is more damage, then I am considering stroking this motor. I am going to show how little I know about motors with my next question.

I know the entire rotating assembly would have to be changed but could I reuse any of the old parts. Heads ? Thanks
