It starts getting expensive from where you are on out... For what it's worth here's my opinion: my YJ currently is entirely new from the Cam on up, ignition (TFI), Holley fuel injection, exhaust and header, new 4.0 head, lifters, timing set, hesco RVOB camshaft only the crank rods and pistons haven't been replaced. And needless to say all that vacuum crap is totally gone. So having prefaced that with my experiences, do yourself a favor and Swap a 350 in it or get a 4.0, or get a 4.0 and stroke it with your 4.2's crank and rods. The 4.2 is a TURD. Especially in the YJ's and late CJ's with early emissions systems. Even with mods and fuel injection it's a woefully underpowered motor if you've ever driven anything with 200hp or more. The 4.6 stroker in my XJ might actually be quicker than my old 95 GT Mustang with 5.0 V8. (These were heavier than earlier GT's and the last couple years of the 5.0 weren't it's best) they put out right under 200 hp (rear wheel) about the same as my stroker, and the XJ weighs less and has taller 4.51 gears. If you're just trying to keep your YJ running then good luck and sorry if I wasted your time, but if you're after more power and performance then punt as soon as you can :) -- Simon "I may be wrong, but I'm not uncertain." -- Robert A.
