Manual trans Options for LA 360

I need manual trans suggestions for my hotrod 42 truck project. I was going to go 727 because I am more familiar with the Auto's mechanically speaking but the more I think about it a hot rod really should be a manual. The only manual trans I am familiar with is the one they used in the trucks during the 80's, I think it was NP435? I know there is plenty of them around these parts. I am curious what others who have more experience with the different manual trans would recommend? Also is there any later model trans with OD that would work as well? I am putting it behind a LA360 and it needs to be able to handle 500-600HP.
