Very good engines, I have one in my '59 Big Bolt that I've owned for six years. They have great torque, I have hauled several loads of rock over four tons, and many loads over three tons. It's also very dependable, I can let it sit 5 or 6 months and it'll fire right up.
Go to
Inliners (Inliners.org) and you will find out that they can also produce a lot of horsepower as well, and are very desirable. When it comes to parts, stock and high performance parts are plentiful.
When I no longer need my '59 Big Bolt, the 292 is staying with me.
