Need a good engine that will fit a 1990 Frame Florida ( West Central)

[rjoyce]

Nasty Mechanical Clank the lower crankcase of the engine... First estimates are to replace the engine...I  thought that I'd check on the message board if there are any good Engines for sale out there?

Does anyone know if the GSF500 engines 2005-2008 with the oil coolers, still have the same bolt pattens and electrical connections?
