"Hello, I have a 1993 OMC 5.8L

"Hello, I have a 1993 OMC 5.8L (351W) in my 21' Four Winns. I am looking for a suggestion to add some horsepower to the 260 - 265 rated I have now.

Any ideas? Supercharger kit or at a minimum better intake? I love the boat and with the stock 8.5-1 compression ratio I do not believe a mild amount of boost will cause reliability issues.

It is easy to find performance items for the Chevy versions, but not so lucky with the Ford. I would prefer a kit specific to my application so that I am not re-engineering the pulleys etc...

Any suggestions would be appreciated."
