FYI, OS' predecessor to the .40LA, the .40FP, was also an entry level engine; a 'pedestrian', if you will.
But it had the whole kit, including a boost port, and did respond pretty well to MCP and a few other hop-ups.

I believe it is still being raced in some current club categories, even though it is no longer in production.


Mine did peel its nickel at the time, maybe in part from being fed 'Cruel Power' fuel...
