WOOHOOOO!!!! found the article on my dart engine. :)

Cool, I used a MP 360 short block as the basis for my motor as well. I spent more than twice that on the 340 short block and they both run the same. I figure I can buy 2 or 3 MP short blocks for what it cost to do one 340. I miss the top end charge of the 340 though. That thing really cooked on the big end.
