New life for an old 340 (stock stroke)
The only plus of a 340 is a possible bigger bore and the smaller journals. Maybe thinner bearings as well.
These points aren’t a win win for me. Well, thinner bearings are, but, I’m not worried about the smaller journals and thinner bearings. The bigger bore is a plus and a minus as most people are not thinking about cylinder wall thickness. Just maximizing the engines bore size and cubic inches.
