Both the "rocketeers"- Olds folks and "rockstars with torquewrenches" the 49-54 Chevy group used to post a ton. Both were defacto "clubs" here on the HAMb in the early years. You can see a ton of cool threads by searching either group
Oh, you mean engines, I thought you meant those jet propelled engines things that put people and satellites in space.
I have this one "under the stairs". I bought it to put into my vintage dirt car because it ran an Oldsmobile during it's championship years (the car now has a built '54 Chrysler hemi). I bought it from a guy who really didn't know what it was, but I have torn it down enough to know that it is a fresh rebuild that has never been run. It is a '51 303 and has an Iskendarian cam of unknown type and a set of adjustable rocker arms.. You can see the Offenhauser dual quad manifold and the Mallory flattop. I also have the adapter to mate it to an early Ford ('32-'48) and later Ford ('49-'64) including a stater "switchover". Also, a set set of Hurst front mounts.
