ICEDPPL with the Cig Flat Deck just crossed 100mph. Took him 12 years in progress to get there.
Making some progress on the ol' Flat deck
357s are one of my favorite boats.
80 would be a more realistic goal, but you would still need a lot of power to get there...and reliable drives.
What power are your 502s putting out?
Getting the drives up a bit in rpm vs lugging them, will let them live longer. Like a transmission, rated in tq vs hp.
It would also make it easier to get power out of the 502s or whatever you decide to re-power.
The Blower Shop is the best around for blowers that I've seen. A relatively mild valvetrain with good heads and 6/71 will get you most of the way to the lower end of your goals. But you'll need forged internals for any reliability.

There's a gentleman in Michigan with a 357 running prochargers on 572's, 900 HP a side if im not mistaken, with Konrad drives. He's running right around 90 GPS. That boat is a serious runner. Reaching 90mph with the old flat bottom boats isn't cheap.
