The compression ratio is lower in an Explorer/Mountaineer motor but the heads are the same ones that come stock on the 94-95 cobra. (if they're the gt40's of course)

302 are 8.2" deck height

351 are a 9.2" deck height


Mustang and Explorer have same deck height 302 5.0L engines

^ Then what changes the compression in these motors? I know a stock mustang has a 9.5:1 but an explorer/mountaineer has a 8.8:1.

Larger combustion chamber on the GT40 heads that were offered on the Explorer/Mountaineer versus the Cobra. Milling them brings it back up.
