4056 Offenhauser 327 350 Chev polished aluminum valve covers 1958 and later
Offenhauser valve covers are the most beautiful in the industry! The original sand casting process is still used allowing the covers to be much thicker than other brands for quieting the valve noise. They also retain their stability for holding the gasket pressure down to the head eliminating oil leaks. But most of all, they are nice, and have the famous Offenhauser logo too. Enjoy the great AAA MARINE PARTS WHOLESALE discount pricing too! This cover has the straight across bolt pattern with an oil breather hole, for 1958 and later. Sometimes these are available without oil holes or with holes in both covers depending on back orders. If you need the staggered bolt pattern for early heads see 3288.
470 conversion kit MerCruiser 3" to 4" exchanger
This kit converts 470 MC 1/0 engines that presently have 3" exchangers (77319) over to our high capacity 4" exchanger. This exchanger is designed specifically for this kit. This is the very best way to handle 470 cooling problems, and is the top-of-the-line quality. This company supplied MC with these for many years! We reserve the right to ship a like brand at no substitute in quality or increase in price if there are supply problems with one or the other. You must buy short length of hose not supplied with kit. (You should really change all your hoses when changing any heat exchanger anyway)
