There are also some small intricacies regarding these engines such as the hand stamped assembly line codes in the "ears" at the front of the block. Be sure you're not looking at a marine block that has the side oiler gallies machined off. The hydraulic marine blocks will have C8AE numbers as well OR will no casting numbers at all. The heads may have hand stamped partial VIN numbers in them, as well. These numbers can be very hard to read at times. Call me with specific questions, I can answer most of them. 248-867-3522
The GT-E's delivered and sold in California (mine for example) used a different smog system. Those vehicles used a different distributor with the casting number C70F-12127-F. This distributor was also used on Cougars, Mustangs, etc..., equipped with the California 390-GT engines as well I believe.
Tom, I'm not doubting you at all. WCCC does also list the C7OF-F distributor for the '67 Cougar & Mustang with the 390-4V besides the 427-4V GT-E. Something interesting to me at least (and perhaps to you to) is that in the Ford Parts Interchange Manual is that they list the C7OF-F distributor for usage on the '68 427-4V up to build date Feb. 6, 1968 and C8OF-G after build date Feb 6, 1968 for the 427-4V. I was also including the C8OF-G distributor so acman63 would know that. John
