Alpha one motor new long block old intake and exhaust, both intake and exhaust have been in salt water, intake has a small hole in the housing part I did several redneck test with light and air on it! It was running when it got hot shut it down hope I didn't spin a bearing but where do I start now replace both? It's in fresh water now do need a different exhaust mani if so a part number do I need to find on the solid one piece old one. Doing a leak down today geez really lost now any pointer or help is greatly appreciated
