A good example is the windage tray above. The Magnum didn't originally come with one but I wanted to add it so I picked this up at Mancini Racing. The description clearly states its not stroker clearanced (I missed it when I ordered it). The tray cleared the counter weights but impinged on a few rod bolts. A little persuasion got the height we needed, but in turn it slightly increased the radius so the outer edge rested on the inside of the oil pan rail. The windage tray was ringed with a U channel edge. With a hammer and anvil we flattened the channel back into the tray. I also had to lengthen the slot in the tray where the oil pickup tube ran across. Total time was about 1/2 hour.
