Really NOT what I wanted to see. I just ran my new engine this past weekend. I also went with the BRC alum mains and thick stud girddle set up. Stock stroke (Molnar crank), +.030" Bore, H beam rods, alum heads, mild solid cam. Pretty much the same as yours, except I did find a good block with the thicker main webbs than yours (and my last one block). And yes, I DID almost run over a piece of my crankshaft. I did run over a piece of my block and cut a right rear slick at 100 mph. To answer your question, I would go back with the BRC set up (it's already bought and paid for!) because I feel like the stock main caps are a "weaker" link than the stock blocks.
