RPMs in WOT

[drbarbara]

I have a V20 powered with a Ford 302 engine and a volvo penta 280 outdrive. It currently has a 14 inch 19 pitch prop. It will max out it's RPM's at wide open throttle at around 3500. I tried a different prop with a 15 pitch and it went all the way to 4300. I have been trying to find out what is the RPM's this engine is rated for but so far have been unable. Any help would be greatly appreciated

Thanks
