Thanks for the replies guys!

Big Chevy, I think my grandfather's '84 C-10 has a valve cover like that one, and it has a 250 in it. | | | | | Joined: Mar 2004 Posts: 3,068 'Bolter | | 'Bolter Joined: Mar 2004 Posts: 3,068 | All I could find was that it's a 1966 through 1985 250CID. Maybe someone with a newer book could decipher the stamped code,
Scott | | | | | Joined: Apr 2000 Posts: 499 'Bolter | | 'Bolter Joined: Apr 2000 Posts: 499 | My book says the 348675 # is for '66-'79 250. The HEI is the external coil type used in '75-76.
The hole on the top-front of the valve cover is the oil fill hole. The one on the side should have a large tube that goes up to the air cleaner. This is the fresh air inlet for the PCV system. The PCV valve is already in place at the rear of the valve cover with the vacuum hooked up to it.

I had already poked around your site before but without any kind of mid point to start with this engine, I was having a hard time nailing it. I pulled the distributor hold down and got the rest readable, it has served to only confuse the issue more....... F0322CCT I am unable to come up with a CCT at this point. http://www.badassmustangs.com/gallery/albums/userpics/10038/IMG_0193.jpg

You need date codes, pull valve cover and check the date code of the head. At this point, it won't mater anyway, we are almost 100% sure its a 250. All parts for a 250 will interchange through the years and you have the best head going.
