Michael is correct, there is work to do inside the case when running anything more than a 76mm stroke.
It truly would be easier to buy a new case already clearanced and opened for 94mm barrels. But you'd have to Hoover mod it all over again. FYI, Scat lube-a-lobe lifters have a camshaft lubricating spray hole in the middle, and have very WIDE oil grooves instead of the usual two narrow VW grooves. They are recommended for Webcam cams. I was unable to drill the case I'm working on, there wasn't enough material to drill the extra oil gallery.
Unlike Stan, I like a longer rod(LOL!). My 78 stroke 2165 has a 5.4" rod, but the 2276 I'm building has 5.5" rods.
The 94mm cylinders require about a .020" cut which makes them 0.040" smaller in diameter to fit into the 90.5/92 case hole.
That uncut cylinder came damaged, it has a crack in the skirt from inadequate packing. I've already gotten the new cylinder, got it machined, and have now built the long block.
Patience with parts is needed today, I tore this motor down in January, and I'm close to finishing now, six months later.
