RIP 340 Onto Magnum swap

What was the deal with your block? Needed a couple sleeves right?

Yea, unfortunately. It was disappointing because it had been rebuilt in 2013, ran very few miles before we decided to do a complete resto mod. So the motor sat, even tho it was bagged and indoors, moisture got inside the cylinders and rusted.

The cylinders were already.040 and beyond cleanup at .060.
