258 swap
Hello all-
Currently I am replacing a 151 wutg a 258 w/T5/Dana 300 into a CJ7 and seem to running into an issue. Once the Transmission was bolted onto the crossmember bracket and I came up to take a look it was apparent that the engine was tilted back, so much so the valve cover is resting against the back of the engine compartment. It seems that the engine needs to be lowered to the same plane as the Transmission however this is several inches. I have several thoughts such as 1) This Trans for some reason doesn't work with the 258 2) There may be another crossmember bracket that raised the TM/TC (not likely) 3)The chasis engine mount brackets are bolted in the wrong place/wrong sides of the chassis or I do not have the correct one2 (bought from reputable 4wd dealer and said they came from a CJ w/258). This is my first attempt at rebuilding and am certainly hoping that I made a novice mistake. Any guidance, pics of 258 chasiss engine mount brackets, would be extremely appreciated. Thank you! |

Re: 258 swap
I would bet there's a difference between the Chevy four banger and the
American Motors six's frame mounts, and maybe a difference between the Borg Warner T4 and T5 rear mount: http://www.----------.com/cj7stablizerMount.jpg Give http://www.advanceadapters.com/catalog/003.html a call.
