New Engine Sitting

[Corts60]

I like to roll stored engines over by hand, maybe once every 6 months. No need to run oil pump. The assembly lube will stay in place with just rolling by hand. I roll it over one or two revolutions, just so the piston rings don't sit in the same place in case any moisture does get in there. Then I fog cylinders and wait another 6 months. Whatever you're doing, I'm sure the engine will be fine.

Just tape off all entry points: intake ports, exhaust ports, etc. I like to use shrink-wrap tape as it is designed to not leave a residue even after long periods of time.

Basic WD40 won't prevent against rust for more than 3 to 4 months at best. Depending on temperature and humidity. Use a more specific rust/corrosion prevention product for long term prevention. My favorite is Fluid Film for non electrical items.
Nice looking manifolds. They remind me of the ones on a Pontiac Sprint OHC6.

Congratulations on keeping that little 250. One of the finest GM engine designs. The small block gets all the glory but a well built 250 is a wonderful alternative. I recently went to a show and saw a Camero with numerous folks looking under the hood, yep 250 six. Some commented “Never Seen One “.
