Been following Uncle Tony on his slant build. Tearing mine down now for rebuild #2. I bought it as a rebuilt ( but not "recent rebuild") This is the first slanty l have done but have prepped a few small block Chevy blocks for dirt track racing. You know, the usual grinding off flash and blending and smoothing oil passages for better flow. Upon removing the oil pump l noticed a little bit of casting flash and sharp / rough surfaces where the oil enters the oil galley down the side of the block. I can't help but think that there should be some sort of advantage in oil flow, both on pressure side and return side, to smooth some of these surfaces. I know Uncle Tony did some smoothing on the block for better oil return to the pan. ( and also a little weight reduction - which is good). But l don't think he really addressed the oil galley. From years of oval track racing l know a 2600 lb car car is a Hell of a lot quicker than a 3200 lb car. Anyhow, what are your thoughts on smoothing some of this stuff for better oil flow. I'm not going to go crazy on it. Motor is a daily driver but will see interstate speed of 70(+) he he.
