rockcrawl: The 302 v8 has higher peak torque and hp ratings than the 300 I6. For a Mustang definitely the 302 is the way to go, but apparently the 300 6 is better in trucks. Ford used the 300 as the base engine in F250s but did not have the 302 as an option. I think the 300 is beefer to take more abuse. Also, Moses Ludel, author of the Complete Ford F-Series Pickup Owner's Bible (not exactly sure of title), said the 300 outperforms the 302 in truck applications. In an F150 seeing light duty use it probably is 6 of one or 1/2 dozen of the other. If I want more power than my current 300 6, I'd go with a 351 V8 (or 460!!!:7). By the way, I love the 302. Had a full sized '71 ford with 4 doors and a 302 in High School. We had a blast in that car and it always ran beautifully.
