I recall that there is little difference between the standard 289 C code car motor and the K code. Most of the differences are minor bolt on items. I remember the exhaust manifolds were the most difficult and costly item to get.


The "K" block has thicker main caps, higher nodularity and it's own casting numbers; C3OE & C4OE-B, which are 5 bolt blocks; and C5AE-E which is the 6 bolt. K code cranks will have a polished mark on front counterweight because they were Brinell tested for hardness. The heads will have factory screw in studs, slots for pushrod guidance and 'seats' cast into the head as a pockets for the valve springs to eliminate walking under high rpm. The hipo 289 rod is heavier and uses broach cut seats and 3/8" bolts. They also had their own cam, solid lifter varity with number C3OZ-C and a VE mark fwd of dist gear, .460 lift and 310 duration. The 289 K engine were anything BUT minor variations of the reg. 289.
For your case, I would suggest putting an ad in Hemmings and on SAAC Forum. Include all the casting and date code numbers and provide a thorough explanation of the condition. You will find a buyer who knows what he needs and will spend the $ to 'make it right' in reality as opposed to just cosmetically.
Good luck!
