I STILL don't have any idea on how 341CI are made from a 239C engine 'cause a 4.5 stroke and really the max safe bore of 3.375 without wet sleeve is still only 322. Piston speed of 3735 (@5000rpm) WILL kill that crank.

Sorry - I cannot believe that Nitrowarrior can't put some sort of graph on line to defend his outlandish statements of CID and Hp - so until then, it's a figment of his imagination.

If there are REAL supporting docs, then I'll be the first to apologize
