ive got an 89 yj 4.2 with Howell injection kit. I live in Dubai and parts are hard to come by for the 4.2 therefore I want to swap it for the 4.0 engine. I want to keep the Howell kit but will this be possible? I believe my inlet manifold will fit the 4.0 but would there be other complications? For example would the 4.2 distributor fit the 4.0? Thanks in advance
4.2 - 4.0 swap
