i don't think alpha water pump will cool that much power. you can scare up an old inboard pump and redrill bracket holes to fit smallblock on other side from power steering and alt.

Oh yeah? Try telling that to all of the owners of 18 and 22 foot Donzi Classics running in the 80s, 90s and a few over 100 mph. https://www.youtube.com/watch?v=1jKhIXJ0fME

I think you would have to be @ 700 rpm or less to be able to shift & have a decent life for the alpha

I'll stand behind this statement. My experience has been 800 an under. 900 and over are the ones I see go boom quickly.

And yes, I've blown these up this way too. So, not just hearsey.
