The 4.2 was gone in 91-92...somewhere around there anyways.
91 was the last year for the 4.2L. The 4.2L motors are used to make the stroker 4.7, I was thinking about doing this a few years ago but went with just the basic overhaual. The 4.2L motors are the same as the 258 6cyl that has been put into jeeps since about 1972 (I think)
