88baja226sport

I am doing a repower on my 88 226 sport Baja the old motor was a tired 454 365 hp and a bravo one drive 1.50 ratio. I had a mirage 23 pitch prop on it. The new motor is a HP500 stroked and the cam is good too 6000 rpm. The guy I got the motor from had it in a baja 270 sport with a 28p four blade running at 5400 rpm with a 1.50 ratio bravo one. I know my 23 is not going to get the job done. I'm looking for recommendations on what prop I should start out with.

Thank you for all your help!

28 Bravo will be a good starting point
