The 340 is out....again.....

The camshaft bearings were destroyed. The camshaft dug down into them instead of riding along on top of them.
It also turned out that the old shop did an overbore of .033 instead of .030, which wasn't a really good combination to have with the .030 pistons.
It now has an overbore of .040 with .040 pistons, and the math works it out to be a 340 stroked to a 418.
Really, and I mean really, looking forward to firing it up and driving it.
