No, the Skyhawk had the Buick 231 CI V6. The 231 was , and still is one of the best motors GM has ever made. They also put a turbo 4 in the Skyhawk for a while.
The first 231 that was put into the Skyhawk was the oddfire V6. These engines had a rough idle because they used a 90 degree power stroke the same as a V8.
The 265 Chevy was an option on all of them I'm pretty sure.
I don't remember a turbo 4 cyl. engine. The only 4 cyl. they had back then was the 151 Iron Duke.
