I have some heads, supposedly off a 427 ford engine. Possibly a marine engine?? The numbers aren't like any I've seen...
The slanted numbers near the spark plug holes read:
575 and 2143
Then there is a 91X under the valve cover area.
Any one have a clue? Are these regular, med riser or what?
Would really appreciate any info!!!
You might try Ford Power Solutions in Anaheim. They build a lot of motors. http://www.f-p-s.com/
Thank you for the tip, I'll check it out...
I’ve been melting pavement with a variety of FEs for 20+ years and professionally building them for almost as long. In those years I've came across alot of strange casting and part #s in the FEs. A couple of years ago I ran across a set of heads from a 352 in an old Police car from New Mexico, C5AE-275-2143-C I was completely baffled !!! I called a friend of mine up in Dearborn (Ford exec. In New Product Development) He called me back and said "Nice one, you had me going for awhile! Next time your joking around with me, Give me a real Head # instead of a Distributor Part Number" It took me a half hour and a some pics with my Digital camera to convince him they where really on the heads. Your heads my be part of the same mix up, Check the #s again and see if you missed any.
Thank you for your post. Your number is very similar to mine. I don't have the 'C-AE' section of the number though... What did your friend say the heads were, anyway? I would like to sell these heads and it would be nice to disclose what they might have been on.
He and the records aval. came up with that # being used as a part # of a dist. He was CLUELESS....................
Good Luck on the ID
Hey Cali grrl; those heads are 1959 for 332 or 352's.
They have decent ports and the same valve size as others, not a bad choice but they aren't 427's. Still, they can me made to perform easily with CJ sized 2.09 and 1.66 valves installed and a bit of porting to smoth things out.
