Was there ever a 4.0 liter in the foxbodies?

[84LX89GT]

Mustangs had an option for a 3.3L, 200ci straight six (same one that was in the '64.5+ mustang) in the early 80's until like '82 or '83
Mustangs also had a 3.8L V6 from i believe '85 to '86...basically mid 80's until '86.
Mustangs had the 2.3L since '74 and there were a few turbocharged versions in the early-mid 80's. '79-'82 carbureted/turbocharged '84-'86 Fuel Injected
The ONLY engines offered from '87 to '93 were the anemic 2.3L and the healthy 5.0L...basically stayed the same through these years with small changes in fuel injection and cams.
Also only offered in '79, the first fox year, were 2.8L V6 engines offered in the previous generation the Mustang II. They had 2.8L badges on the side to distinguish them (why Ford did that....i don't know).
Ford also dropped the 302 for the small bore, super smog 255 Windsor which was 4.2L and 119 horsepower for the years of '80 and '81.
I believe that covers all the engines i can think of.
