So seems you did alot of experiments and I'd love to see if I can get my eagle, near where were back then.
I'm going through the hp 500 502 now, never opened, still had Mercury racing lead sealed safety wire.
I'm planning 572 stroker or basic 502 rebuild. I plan to add a supercharger, extension box etc as time, money allows.
My question is what about adding a turbo 400 trans? I'm thinking with the extension box, it could fit? I'm planning EFI when I add the blower.
Just wondering what your suggestions are for the best go fast, 26 close now eagle would be.
Thanks Bill

did i read that right??? Th400 trans…..please elaborate???

The Skater that crashed in Arizona runs a TH400

so he literally had 3 spds, i mean how does that even work and why dont we see more boats with multiple spd trans setups…..so like do they run the setups like youd see in a car???
