FE Cylinder Head ID Question
New member to the site here, have a good question for everyone. I've got a 390 in a '76 Ford F250 4x4 that I am in the process of disassembling. Pulled the heads off and found the part #, which is C0307048, stamped into one end of each head, not cast-in. I'm just trying to figure out what year of heads these are, and any other helpful info 'cause I'm not sure these are the original heads. I have tried a Google search for this #, and no luck. Tried a search on this site also, but no luck there either. Can anybody figure this one out? Thank you!

That sounds like a rebuilders stamped ID number for warranty purposes. The FE head ID is cast into the head between the center two exhaust ports on the surface next to the spark plug holes. It will be raised cast numbers ie. D2TE-A. HTH

there will be casting numbers on them anyway! They are by the exhaust ports. The casting doesn't always tell you the correct year! The castings could last a couple of years. fyi c is the 60's decade, d is the 70's and so on. The number such as 2 is the year. D2te are 1972 heads but could be on any1972 and after engine.

Not to toss too big of a wrench in here but, the 4x4 trucks did not come with a 390, so you "may" have a 360. If the motor is original to the truck tell us what the first four digits of the VIN are off the driver door (F26x) where "x" will tell what motor was factory. Ditto on the head numbers info...

Thanks for the replies guys. I did find the cast #......can't figure how I missed it before. The # is C8AE-H. The engine is definitely a .030 390. I measured the stroke with a tape, reads just a tad over 3.75". The shortblock assembly looks pretty good, very little ridge at the top of the bores, very little scuffing. The heads appear to be in good shape, in that all the combustion chambers were dry, no leaking oil past the valves. This engine ran pretty strong in the truck. I could almost start out in 3rd gear, and it still needed a tune-up. I'll be using this engine in my '74 Ford F250 4x4 as the original 360 is way too gutless for my liking.

This really bugs my bum! Ford put the 390 and 460 in 2wd trucks yet they like to put smaller motors in bigger, heavy, work trucks. Go figure! When i am looking for a 4x4 machine I want a truck not a slug. Then they put these little 215/235 15 inch tires on trucks with 390 and 460s and then people complain about traction and their massive burn outs. I have found that i like traction more than being able to roll the tires up in smoke. Burnouts do no good on gravel with a load, snow, mud, hills, etc.

Matt,
You can always do what brian did to get some low end Grunt amd build a 511? stop and think about it tho..I dont recall any of the big 3 putting there big blocks in there 4X4s...the all had small Blocks...I think it might have been done for insurance and Liability reasons? Just my guess? Russ

C8's were standard issue late 60's heads on these motors. They did not have hardened seats installed and were replaced by the D2's in early 70's, which did have the hardened seats. I'll guess here that your motor received these heads rebuilt, when the engine was done, and probably now have the hardened seats in them...
Happy building --Mike
