here check it out they did make a 351 saleen. I saw one at a car show with a vortech on it. It was a goldish kinda camealein(i don't know how to spell) color. Lets see if I can get a pic from somewhere. It doesn't look much different then the normal s281 but, just with the badge that says s351.

 

the 351 clevelands weren't half the engine that the 351 windsors were, my dad had on of each and the cleveland was complete junk, don't know any exact numbers though

 

I had a 351 Windsor in a Gran Torino and it was a piece of sh*t!

 

i always thought the Windsors were crap. i have a 96 bronco on 42's, it has a built 302, a couple of my buddies had 351 Clevelands and they were tryin to convince me to drop one in mine. maybe im wrong.
