Thats very cool for All Yellow. seems kinda old school.
What performance would you expect from the sbc's, and compared to 275OBs?
I'd say this sbc b1 package would be bulletproof and w/ a 5yr warranty... cool!

Still hard to insure i guess.

I was looking at this boat what mph could be exspected the way it is,and set prochargers on those smallblocks?

I am guessing here but with the small blocks I would say right around 100mph and the prochargers you would be in the 110 to 115 range.
