Anyone know the GM part number for Merury part 431-811658? This is for a roller cam out of a 1993 Mercury (GM) 350 Magnum (5.7L) Tournament ski boat engine ( was in 1993 Sea Ray "Ski-Ray" competitive ski boat.

Are there other cams comp/crane etc that can be a suitable replacement? Stock application - don't have dollars for upgrading valve components

thanks,.

Carbureted ?
Ck to see if the following has a fuel pump lobe. If it does, this maybe a decent choice. Lower cost than most and still usa made.
