UTG engine build "callout"
Ok, what we have here is a typical run of the mill 318, although this is a magnum variety, a 94 casting I believe. This engine is here in order to grow in to a 390 inch mill, but that's another story. With the stock crank, and std bearings in place, the piston is "in the hole" .052 as installed from the factory, notch to the front.... Flipping the piston around, it measures .053 in the hole, with the notch to the rear. So a grand total of .001 difference, and then consider your running probably. 0025-.0030 rod bearing clearance, I'd say its basically "net zero" I did confirm the piston has wrist pin offset, although I didn't measure the amount, the .060 @RustyRatRod spoke of is pretty close.
