My boat has a bad engine, 4.3l v6. 1990 , can I upgrade to the later mod engine 4.3 with the vortec style, knowing that it has a balance shaft above the cam on later engines, would there be any phisical differences in bolting up and in the configuration? My boat has a 4 barrell holley carb, so any help with the up year upgrade, say a 1996-8?
