My old man raced mini stocks and Outlaws for years using this engine and has done all kinds of tricks to pull just a little more power. Even turning down the aux cam and making his own flywheels. As far as I remember, he never did this on any of his engines.
Okay, a few months ago (more like in the summer) I was at the hydroplane races and the guys there were all running 2300's in their boats. I watched one of the mechanics put a new head on his engine when something weird happened. He set the head on the block, put some of the head bolts in loose-like then shoved the head to the back of the block. I realized he didn't have any dowels in that SOB. Then I started thinking... (obviously not fast enough because I didn't think to ask)
Does this enhance performance at all? I mean, the offset of the combustion chamber can't be easy on the head gasket, but does it raise compression or what? Clearance for bigger exhaust or intake valves? (Honestly I don't know because I haven't looked closely at one of the heads for almost a year.) I don't know any of the rules regarding valve size, cam, or crank stroke or what kind of fuel they are using.
I wouldn't do it on any engine driven more than a race or two, but I am curious. There has to be something to it because the guy went out and won after that...
