Default 427 Casting Numbers

As "Dwighy" suggested to you earlier, you should order the book "High Performance Ford Engine Parts Interchange" by George Reid. There are quite a few photos showing detailed locations for numbers and lots of other information unique to each specific engine series. It will show you how to identify a sideoiler from a center oilier. There are tables in the back that list all the engines for each year in the 60's and 70's and the specific casting numbers used for each engine type. Same for heads and other engine parts. It is a very complete book full of excellent information.

Question, does your block have the distinct ridge along the lower left side of the block just above the crossbolt main caps? The ridge will be parallel to the bottom edge of the block. If yours has the ridge as well as the small plugs for the 3 center main cap journals, it is indeed a sideoiler. If those features are not there, it is not a sideoiler.

Get the book, you will use it over and over.

Good luck, Bob
