I pulled this from a 1985 Jeep CJ7 with a T5 transmission. It is an I-6 that looks like the AMC 258. It cannot be a 258 because there is no place to mount a mechanical fuel pump and the block code has 7 digits. It is an AMC engine because is has the AMC logo stamped on it. The block code is 808MXII. I called 2 local jeep dealers and they have no info. What is this engine? Thanks, David.
