someone school me on my A833 for my swap Please

I'm also going to run my 318 for now until I get my stroker done that way I wont have to swap from external to internal balanced on the flywheel.
What kinda power will this overdrive unit withstand? Is it going to ok for a mid level stroker engine? I've lightening the car so I don't thing there will be a lot of weight to push around.
