351W block dipstick

[omureebe]

The '69 Galaxies did have the 2 barrel 351. I did a lot of searches in the '80s for 351 4 bbl donors. So I guess the 2 bbl 351s were just overlooked. I did own a '69 full size Ford but it was a Custom, the Police and taxi low buck package. Mine had the 428 PI engine that easily outperformed the 429s in Galaxies.
I can't help but be curious why a '69 351 block casting had hole had too small for a dip stick. What was it for? The later 351 blocks at least until the mid '90s had no hole in the side.

My current "best guess" is it was done during the first rebuild, prior to me owning it. I'm guessing the machine shop added it for some reason, as it all looks wrong. Time for the wooden dowel with some rtv and new oil pan...
