Several years before Janet and I bought our 427 powered 38, we looked at one on Tims Ford Lake that had a pair of 545 Ford Seamasters, and ladies and gentlemen, they were georgeous!
The 534, in case people are not familiar with this particular motor, is the "ROYALTY of the gasoline workhorse V8 world". It was used in fire engines, large busses, and lots of other heavy industrial uses. I have no idea how this motor got into a Chris Craft, but I suspect it was a custom order. We would have bought the boat, but it had been used as a dive boat in Florida, and that scared us off.
Since then I have always looked for another Seamaster installation, and so far I have never seen another one. This has to be the strongest and most durable gas motor ever installed in a Chris Craft boat, now, then, ever, with no close seconds.
This motor has a family tree to the 430 Lincoln series Chris Craft used, but with 534 cubic inches of pure industrial strength, it's far more motor, and I suspect it was very expensive too.
For your reading enjoyment!
Here is a link to more info on this awesome motor.
