| RE: 390GT vs 390 IP |

| the main differences between the 68 and older GT and the 69 IP engines were the distributor, carb, intake, and cam. these items were changed to improve emissons and economy (although rumours do circulate about the engine being de-fanged to make the CJ look even better). all 69 S code cars came with the IP engine. the GT package was a trim and suspension package on the car and did not have anything to do with the engine chosen. the info you got about heads is the biggest bunch of malarkey i have read in a while. the C8AE-H GT heads are are simply the standard high velocity smog head with a different bolt pattern on the exhaust side. the head is a good head and has potential for performance. all of the C8AE-H heads came with the same size valves no matter what the application (these heads were used on all 68-71 360 and 390 engines in pickups and all car lines). your grandmas galaxie with a 390 2 barrel and grandpas F100 pickup with a 360 2 Barrel had the same heads and the same valves although there are different valve springs for performance applications. hawkrod |
