I used to scavenge up every "worn out" small block 4 bolt main bearing block any of my competitors were discarding, for pennies on the dollar, or sometimes free. I had an engine rebuilding program as part of the course I was teaching, and my students needed blocks to practice on. The next time a lot of those guys saw their "junk" engine it was diving into a turn ahead of them, with 8 new standard bore sleeves installed. The rest of the race block preparation had already been done for me- - - -free of charge by the guys who thought they were discarding junk!

After a while, it was hard to scavenge up any "junk" from a competitor!
