Sorry for the ‘ad’ but I thought Id get better exposure here. I’d like to buy some Nelson shortstroke Q500 engines. I need the last SS version before the Q500-LS became dominantin 428(the SS-Q500 is our prescribed Canadian Q500 engine with different muffler). So if you have any newish /real nice shape collecting dust, you’d like to unload, please email me directly with asking price, condition, track record - example: shortly after gentle breakin this engine went on to win the US Nats in 2007...
