Engine swap (Looking for fabricators advice)

[Scot Rogers]

I have a 1988 Four Winns Liberator that I am repowering. I am replacing the OMC 350 with one of the 350 "Power Pack Specials" you can find everywhere. It's a 325 hp. 350 Vortec roller with a Holley. My question is, has anyone done this type of swap, I need some advice with mounting the shift cable bracket to the Vortec manifold ( I know I will need to fab something, but I was hoping some of you could give me an idea).<br /> Also this new engine has a Mallory elec. distributor, the old one was a points type. According to my Seloc book the wiring diagram shows the ESA mod. ties only into the neg. side of the coil. So I should be able to do the same with this set up (?)<br />Any help would be great!<br /><br />Thanks guys<br /><br />Scott Rogers

You'll undoubtedly want to get that distributor recurved. Or better yet get a marine rated distributor. If the one you have is out of an automobile it will not meet USCG specs and will have a curve that is not suitable for a marine application. Also the automotive camshaft could result in rotten performance.<br /><br />I'm facing the same issue with my ford/edelbrock intake conversion. My throttle cable bracket was built to bolt to an OEM intake. You'll most likely have to fabricate or see if something like this would work.<br /><br />

Is that "Power Pack Special" a marine setup? If not, there is more than just the distributor that needs to be changed to make a marine engine. Including, cam, head gaskets, core plugs, carburator, fuel pump, starter, and alternator.<br />Most have to do with spark and fuel leak problems in an enclosed engine compartment of a boat. If it is marine, then it's no problem.<br />That shift bracket does not have to be on the engine. I have seen them mounted on the transom and the work just fine. The engine was just an easy place to mount them from the factory.

It's a marine engine. I purchased it from marine-engines-inc.com they are out of Holliston Mass.
