so my buddy got a YJ with the little 4 cyl in it and he wants to do a 4.0 swap. my question is will a 4.2 intake bolt onto a 1990 XJ 4.0? also will distributors interchange? see, summit sells that mopar fuel injection kit for a 4.2 and it comes with a new intake and distributor and whatnot and i dont want to have to use all that crappy Renix stuff thats in the 90 XJ in the yard.. any info is appreciated
