"Not sure what rotation you ha

"Not sure what rotation you have.
Standard engine rotation is LH, meaning if you look from the front, all belt driven parts are turning CW.
Is the 350 a marine engine?
If not, it will not have a marine cam, valves, head gaskets, oil pan, distributor, carb, or frost plugs, for starters.
If the rotation is the same, most all external parts should swap over though.

"It should just Bolt Up,+

"It should just Bolt Up,+ Run.........
Last time I checked,.... 1980 is right between 1979,+ 1985........
I don't see the Issue, or the Question........"
 
"LIke Bondo says, if its a mar

"LIke Bondo says, if its a marine crate engine you should be good to go.
Check the drive ratio; you should have 1.50
