what cam did you use?dropping a rebuilt 258 into mine as well-same that was in it with some mods. Did a 30 over on the pistons, new cam, header, intake, dui distributor, weber carb. Asked around much like you are and any "old" mechanics said either motor is reliable if taken care of.
Welcome to the Forum!what cam did you use?
Welcome to the Forum, from Cave Creek AZ.I have a 1988 YJ with an odometer reading of 125,000, owned for 2 yrs now, daily driver. I'm wary of that ODO reading, although it was mainly used as a toad for past 5 yrs (all wheels on ground, xfer case in neutral -- I hope). It has the original 4.2L, 258 engine. One great solution for the carb problem is to get a Howell Throttle Body Injection (TBI) system. It's a little pricey at ~$1,500, but it is oh so nice. Mine came with it, but due to poor maintenance by previous owner, it needed some TLC. I studied the TBI system and replaced 3 sensors (cheap at Autozone). Very sweet engine now. Next I want to replace the timing chain, tensioner, and possibly the cam shaft to squeak out a few lost HP. Distributor timing curves aren't ideal either.
