Thread: what is it

It's a basic impeller type super charger. Mc Culloch use to make one very similar to that. It's sometimes referred to as a "pie tin" supercharger.

First time I ever handled one was in 1967. We were stationed at George AFB near Victorville Ca. My buddy and I rented a garage made from converted horse stalls. I was building my first '55 Chev he a '36 Ford pickup. We were looking for an engine for his truck, and stopped by our favorite wrecking yard. We told our guy behind the counter that we were looking for a decent flathead V8 since they were really cheap in those days because most of the rodding world had long moved onto overheads. He said the magic words, "I think I've got just what you're looking for." He took us into the back of one of the sheds and pointed out a couple wooden crates in the corner, covered with some dust. In the boxes were a fully machined block, crank, rods, new pistons, rings, bearings, cam, lifter, springs and more, including a full gasket set. Oh, and the aforementioned Mc Culloch supercharger, though it was used looking. Cost a whopping $25 for the whole shiverie! I'd only ever seen pics of the supercharger in old magazines, so it was neat to have one in hand. Never did get to see or hear it run though since it wasn't long after I got to go visit some heavy jungled place.
