WOT Chevy 350 4BM??

[Fishy McGee]

I've replaced the 305 in my 79 V-20 W/OMC 800 with an S&S remanufactured Chevy marine 350 with 4 bolt mains. I haven't been able to get a straight answer from anyone at S&S as to what WOT should be(I think I'm talking to counter sales people without a clue). I'm trying to size a prop and don't know what my WOT RPM's should be. Anybody out there in V-20 land have some info for me??? Please....Pretty Please......
Thanks
