GMC engines were pressure lubrication when the Chevy Stovebolt Six was still splash lube, with dippers on the connecting rods. So before the small block Chevy was a thing, the racers that didn't run flatheads or hemis, ran these. 270" and 302" versions were in the medium duty trucks, and in the one tons too IIRC. Surplus military trucks ended up on farms and the engine sometimes ended up in a race car....

The Miniature Engineering Craftsmanship Museum (MECM) in Carlsbad, California has an amazing number of miniature machines, include operating engines.

A person can easily spend half a day there.

If there is one thing that makes me want to visit CA, that is it.

Talking about old technology…

Remember the sleeve valve engines of the early 20th century? I couldn’t believe they existed until I saw one in a museum with the engine cut-away to show the mechanism.

I might have seen it at Bill Harrah’s museum in Reno when I was attending the Air Races a few years back. That’s a very impressive museum.

Gotta love the old venerable Rocketdyne F1 engine. We're talking about all these old GMC engines, but this thing here was designed and built in the 50's and 60's and used a 55,000hp gas turbine engine AS THE FUEL PUMP, to pump 414 gallons of liquid oxygen and 258 gallons of RP1(kerosene rocket fuel) per SECOND. The Saturn V first stage had five of these running at the same time and flowed enough fuel and oxidizer to empty an Olympic swimming pool every 3 minutes. Each engine generated 1,500,000 lbf of thrust.
