Buy, borrow, or steal the book "Small Block Chevy Marine Performance" by
the
GOD of GM marine engines Dennis Moore.
Read it cover to cover and it will answer all your questions.
Amazon, eBay, or www.mooreperformance.org
Dennis has forgotten more than anyone else will ever know about GM based
marine engines.


Dennis is an excellent STOCK Mercruiser mechanic. PERIOD. He is 10 years
behind the times whenit comes to anything high performance.
