I decided it was time to replace the spark plugs and tune up my engine a bit. I pulled the spark plugs an tried to clean up a bit. Under the grease were the engine casting numbers so I decided to look them up. The casting on both sides reads " C8AE-H" Looking this up on a casting number reference it says:
" C8AE-H '68 427 c.i.d. Hydraulic Lifters, Side Oilier"
Also on the left side front of engine there is another casting that reads "13" "352"
By the VIN this 69 F-250 should have a 360 but the castings say otherwise.
What do you gentleman think?
if it is a 427 what do I need to know. Can't find to much info on it, except people saying its "rare"?
P.S. Please excuse the dirt and grime in the photos, The P.O. didn't really care about keeping things clean, so now it's my job to clean it all up!
One way to know if its a 427, is on the lower part of the block, should be 3 bolt head, Per side, that are along the lower edge, Simply take a pics of it and post, if there the right one, you have a 427. This is for the 4 bolt main, and only a 427 has them
In the "Big Block Ford Engine book by Steve Christ, Page 55
Head C8AE-H is a standard 360 head, for 360,390, 428 w/air Chamber Vol is 68.1 to 71.1
If it ante broken dont fix it.. If it is.. hit it with the biggest hammer U can find :P

Reason: added info
Pull a head and measure the bore. My experience with the casting numbers on these motor is well, not there half of the time and they did all sorts of goofy stuff. I have a block with the 66-427 cast into the back and the side oiler bosses but it has standard 390 cores and the oil galleries don't run down the side. Between all the industrial and marine applications there really is no way to know until you see whats inside. That head is one of the more common ones and not a 427 head. If I was a betting man I would say its the original 360.
NumberDummy, based on the information you supplied about the heads, does that mean that the same heads were used on 68-71 360/390 and 68/70 428? Excepting 1967 428 P/C's with T/E, 1968/70 P/C's (Police Cruisers), 1968/70 CJ's and S/CJ's.
I guess what I'm asking, did all of those engines use the same part number heads, valves, etc?
The reason I'm asking is that I have been undecided as to whether to find a good, used 390 for my build, or just to put 390 internals in my 360.
Am I making sense?
The same C8AZ-6049-M head was used on all these applications, except as noted above...plus it was a service part replacement for 352/390 heads used from 1965 thru 1967, ditto for 410/428 heads used 1966/67.
Look in your 1964/72 truck parts catalog, section 60.7. What head part numbers are listed for 1965/72 FE's?
C8AZ-6049-M without T/E, C8AZ-6049-A with T/E. CA passenger cars, F100's had T/E (smog pump) in 1966 (after 1/1/66), 1967 and on some early 1968's.
The 1972/73 heads have a different casting number (D2TE), but the part number remains the same.
