SB engine identification

[vettestr]

Hey all you SB gurus,
I am going over to help identify a 289 or maybe a 302 for a friend. The wife has no clue what her late husband has tucked under a tarp. It could be a circa 70's up to maybe late 80's engine I would guess, has finned Cobra V covers for what the little that means.

I need a push in the right direction, where are the numbers and date codes on the block and a head. This engine is assembled but I can pull the valve covers or what ever is needed. THANKS for your help. Jeff C

I am editing to add the E to cast number. The E makes this a correct date and code for a COBRA

It was a 289. The block is # C5AE-6015-E dated April 19 of 66 with the heads coded C6AE and dated Feb 21 of 67.

The heads have had all seats replaced and looks like new valves and springs too. I am guessing guides were replaced but adjustable rockers have been installed and guide plates have a Ford part # visible. No porting or gasket matching has been done on the stock castings.

The block is a 4" bore as measured with dial calipers only. The bore is a fresh hone with no rust or any corrosion visible from storage. The pistons are flat top with eyebrow valve relief's. Deck does not appear to have been cut.

I will list this in the for sale area with photos later tonight
