Hi, could anyone give me a breakdown on a 6 cylinder I have? CE 6015 B
I believe it is a 250ci but not sure or what it came from. Thanks.

 

The 250 was a 1969 offering, so it is possible a C8... casting number would show, as production would have started in 1968. I take it this engine has the integral intake on the cylinder head?

The only other SB6 would be the 200 for '68 and up. The deck height and bell patterns are the main visual differences, explained here:
