To hammer home our point of always looking before you leap, here’s a nice little Olds small-block. But wait; it’s not a snortin’ 403, 350, or even a pedestrian 307. It’s a 260, as indicated by the heads’ 2A casting. What’s worse is that this dog is bolted in the engine bay of an early ’70s GMC pickup and some poor schlub had already made off with the tranny. We just hope he realizes it’s a BOPC bellhousing pattern and not a Chevy before he drops it at the rebuilder.
