Slow Cranking Engine
I just had a 350 dropped in my truck to replace the old 305. The problem is the 350 cranks REALLY slow, even with no spark plugs installed. This engine sat for a few years in a wrecked vehicle (without being ran) before I bought it. Could this thing be trashed? I hate to give up on the truck, but I'm NOT going through another engine swap. If anybody has any ideas on what to try, or look for, I'd love to get some input.
I put Marvel Mystery Oil in the cylinders before we even started the engine swap, and let it sit. Also, I replaced the starter with a known good one. It doesn't act any better. Thanks for any ideas that you can dish out!
