Mustangs could have an inline 6 from 79 to 82 or so. The 3.8 first appeared in Mustangs around 83 or 84.The inline six was not an 80 mustang that I know of. It had a carb'd 3.8 v6 Just like the newer ones. 1986 was the only model i ever saw though.
The 60's had the inline six it was the first motor ever in the mustang.
Is it possible to swap a 80's Mustang engine (200 inline 6) in to my Ranger?

I had an 81 Mustang with the 200 inline w/4 speed; one of the best motors I've had especially at 35 below zero plus wind chill. My question is what transmission bolts up to it in a Gen 1 Ranger?
x2 on hidesertlivin's question about tranny's. i have access to a 250 that i would love to put in my truck if i could bolt it right up the 5 speed already in it. had a 250 in an old mail van that had excellent torque and power. had the 200 in a 1966 mustang i once had. it felt to me like the 250 had more pep and power even though that van weighed more than the mustang.
