Wondering what I have. Engine block, never used.

Hello Tauro, Sent you a PM. Thanks, Matt

TAURO Micking the bore would be the first thing to do. What is the black line in picture #3 along the camshaft tunnel on the back of the block? It looks like a crack. I agree with the service block replacement. Does it really matter what year it is? It's a good find. If you are going to store it for a while, spary it with WD-40 and bag it. You need to stop the rust both inside and out side of the block. Rick L.

-Are the huge plugs the main thing that indicates its a 427 side oiler? I have seen the same ribbing on the 428 CJ engines, but i dont remember plugs that large.

-I dont see a black line in pictures 3, just thread sealant that drooled down from a plug and a shadow.

-Dont spray it with WD-40 if you plan on storing it. Over time, WD-40 will glaze and turn into something that looks like a peeling polyurethane coat.

I found Aerokroil from Kano Lab. in a spray can to be the best. We can buy at some of the part stores or supply houses.

its a service block for sure.....if the bores are 4.236 its a 427 side oiler.
will probably have no casting number other than casting date code.
that will be by the oil adapter mount. this will tell you what year it is.
the service blocks are usually from 1969 to 1974 ish....

The crack is on the left side and follows nicely along the contour of the block. At first glance it looks like a shadow. It is non-structural and could be welded (I think). Maybe it is a shadow, . . . can't be sure.
