Hello. I’m brand new to this site. I have an engine question. 25 years ago I purchased a brand new still in the crate 413. Block 2205697 head is 2406516-2. The engine has mechanical tappets. Bore size is 4.19. A very reputable performance engine shop has verified that this is indeed brand new never started. They are in the process of doing a complete tear down, cleaning, installing hardened valve seats, etc. I’m going to have it put on a dyno as well. The engine is red from the factory with no stamp on the block yet. Any ideas on what year, and application for car that this may have been used for?
