| 390GT vs 390 IP |
| By Warren B. - 10/15/2002 3:12:15 PM; IP 207.34.111.14 |
Hello. I'm requesting help on 2 issues:
1. I have a 69 390 Fastback, numbers matching (ie. build sheet matches buck tag.) When I wrote Ford Canada to verify my car, they listed the engine as a 390 IP engine. Since my car came with all the features offered on a GT for 69 ( only 5396 produced), shouldnt' my car engine be listed as a GT? According to this website, FoMoCo reports that the S-390GT and
S -390 IP were different motors. It also lists that the S 390 GT was used for the 66-68 Mustangs and the 390 IP was used for the 69 Mustang. Does anyone know if
any 68 S 390 GT factory engines were placed in the 69 Mustang body? Does one need this engine to be a true factory 69 GT?
Since the Cougar, Fairlane, Montego and Mustang were supplied with the 390 IP engine according to this web-site, what would then make a 69 Ford a GT?
2. My heads show a casting of C8AE- H. I have read chat lines that these are 390 GT heads. One person reported that these heads originated from the design of the 427 C3AE-H low-riser heads. The GT heads were then machined in different sizes for various valve sizes, according to what the owner wanted. This apparently would show up as a letter "G" under Performance on the build sheet (which I have.) Does anyone know if the C8AE-H GT heads came in different sizes and if the above info is true?
Thank you! Warren B.
