Basically like Shooter said, it was an unlimited modification N/A 400 inch class, Later they raised it to match the SS class which had very limited modifications at the time. Eventually SK became Pro Comp, then Pro Stock with 500 inch limit.Quote:

Also, according to the old timers I've talked with, the SK class required the boat ran a fixed cav plate. It could have an adjustable locking handle that you could set and leave be, no override pedal allowed.
It looks like in the 1972 deal that Shooter posted they just started to let them adjust the plates while running. Very cool info...
I was going to say, for the sake of safety alone, I would be surprised if they hadn't adopted the pedal override by the early to mid 70's.Quote:

My pleasure Ryan.Quote:

The class was started with the advent of the v drive flat that had taken over ski racing. Like Shooter already said, SK was the designation for SKI boat. By 1958 the design was selling extremely well and was the boat type of choice in ski racing. Prior to the v drive flat, race boats were direct drive cracker, hydros, and service type boats like a Chris Craft type hull.Quote:

The hemis won a lot of the first marathon races, todays GN, starting with the 1959 Orange Bowl 9 hour in Florida, and the first Salton Sea in 1961. But by 1963 the Ford FE 406 and 427 took over and lasted well into the 70s.
SK was the first v drive flat bottom class in APBA, all the others stemmed from the SK class, with different engine sizes and specs.
Thanks for all that history Bob! Much appreciated!
On that note...I'll keep this thread going with some of Leonard's old sleds... :thumbup:Quote:
