9F26= June 26, 1969
Center oiler block. Only production car that used this block with a date that late would have been.....NONE! OK, the 1968 Cougar XR7G used this block "version" in it. Automatic trans.....only! What a waste!
Heads are std variety as stated prev. Not worth poo.
Rods are Cobra Jet or PI, or standard 427 rods. 19/32 socket required....only time you will probably ever use that socket in your tool chest!
Second motor is NOT a 427. No screw-in freeze plugs, no side bolts. Check the bore....could still be a hipo 390 or 428, but you need to see in the block, to check the main cap webbing for the improved version. There will be a date code on it too, by the
oil filter adapter pad.
If the 427 was a side oiler, only then would you have a true Cobra version. This being said, the value takes a hit. $1500-2000 could be a pile too much of cash....unless the crank has $$ cast on it....even then, it could be a wash at that price, AND, you could have a pile of FE that isn't much different than your neighbors old F250 pickup engine!
If this was run in salt water....check the inside castings to see that they are not all rotted away! I'd check to see that the crank spins true as well....many boat engines got swamped.....and problems....!
