US-86MJ Posted March 26, 2013 Share Posted March 26, 2013 2.5 I-4, AX-5, 231(drivers drop)...INSTALLED 258 I-6, T-4, Spicer 300(passengers drop)...waitin to be dropped in... My question is..if I have an AX-15 from a '90 4.0 I-6..will it bolt up to the 4.2L I-6? If not, what other transfer case can I get to fit the T-4 that is drivers drop.. OR..... what manual trans can I get that will bolt to the 4.2L I-6? Doin this swap ASAP!!! Thanks for the time and direction in advance. Link to comment Share on other sites More sharing options...
US-86MJ Posted March 26, 2013 Author Share Posted March 26, 2013 Looks like the AX-15 off a 4.0 will bolt to the 4.2 bc they are bolt small bellhousimg bolt patterns...can anyone shed some light or confirm this? Link to comment Share on other sites More sharing options...

US-86MJ Posted March 26, 2013 Author Share Posted March 26, 2013 Do you have any info on the 4.0 head onto the 4.2 block? What about 4.2 conversion to TBI? Heard of both increasing gains of 40+HP apiece? Link to comment Share on other sites More sharing options...
87manche1 Posted March 26, 2013 Share Posted March 26, 2013 Do a google search there are passages in the head that need blocked of for a ho head to 4.2 other wise yes works. Jb weld for these areas Link to comment Share on other sites More sharing options...
zackcj7 Posted March 26, 2013 Share Posted March 26, 2013 Just buy a Dana 300 flip kit and make it a drivers side drop. Link to comment Share on other sites More sharing options...
ftpiercecracker1 Posted March 26, 2013 Share Posted March 26, 2013 Hell now that you have a 4.2 you can build a 4.5-6 stroker. :rock on: Link to comment Share on other sites More sharing options...
US-86MJ Posted March 26, 2013 Author Share Posted March 26, 2013 Can't I just use the 4.0 intake manifold? Flip kit..I could but I already have a AX-15 and NP231 that are bolted together..just gotta bolt up the bellhousing to the motor. Stroker is in the future plan, as of now, I gotta be ready for an event Memorial Day Wknd. Link to comment Share on other sites More sharing options...
87manche1 Posted March 27, 2013 Share Posted March 27, 2013 The 4.0 intake will bolt up but won't give 40 hp theyre good but not much better than factory 80s carb manifolds Link to comment Share on other sites More sharing options...
US-86MJ Posted March 28, 2013 Author Share Posted March 28, 2013 Thanks for the insight...probably just stick with the stock 4.2 manifold until I can buy a Clifford's Performance intake manifold. Headers will be first tho and a cam is already on the way :D Link to comment Share on other sites More sharing options...
