Old 302?
Tearing apart my old 302 I found some strange things in there.
The cylinder heads are C9TZ and C8OE and #7 piston 8 .030 , the block #D2
This was a rebuilt engine with a tag C8AZ on it? The rods are all D1OE-AA
# 7 and # 8 were not firing and have not figured out why yet? Any ideas out there? It was a points ignition and that is where I think the problem was!

You've got mismatched heads there. Different combustion chambers. Never seen D1OE rods. And with the D2 block, sounds more to me like a 351W. The C8AZ is a part number for the reman assembly. Fred Jones rebuild?

This was a rebuilt engine from eastern rebuilders ltd with a model tag C8AZ-C on it? The rods are all D1OE-AA

Still think you've got a 351W there. Pull one main cap and measure the diameter of the bearing surface, across the cap. 351W will be 3.00" or a little better. 302 is 2.25". Another indicator is the head bolt size. 302 head bolts will screw into the bellhousing bolt holes, 351's won't, they're bigger 1/2NC vs 7/16NC for 302.

They do appear to be mis-matched combustion chambers. c8OE is a 68 is a 2bbl head with 63cc chambers (unless it is c8OE-F which would be 53.5cc for a 4bbl). The C9TE is a 69 truck head which is 58.2cc. The date code on a block is for a 72 engine, not sure which, but should be stamped in the lifter valley. I would think the cylinders should still fire though.

just becouse something is stamped one yr doesnt mean they didnt use it in a newer yr, i pulled the pan off an 86 302 out of a merc. and the rods said early 70s. my point is why improve what has worked for years is what they were doing

When it comes to rods, the 302's used the same C8OE forging up until the early 90's when Ford switched to the F1TE rod (which in my experience was a step backwards)

Ford casting numbers, part numbers and date code numbers are three totally different things when it comes to dating an engine, or other car parts. Date codes are the ONLY sure way to date a part. The casting number on the part (or stamped in the case of other non cast parts) only tells you approximately when the part was first used in production and as you've told here, it can be used years afterward till some other change was needed, for whatever reason. The casting number is NOT the same as the part number, and should never be confused with it. Any Ford parts person will tell you this.
