so, i dunked my jeep, and after 2 weeks couldn't ever get it to run right again, so next week i'm swapping the motor. i've swapped a 4.0 HO into a renix jeep before, so i know what that entails, but this time, i'll be swapping in a franken-motor that is comprised of a 4.2 block with a 4.0 head on it. i know the motor runs fine, and i've known of some cj and fsj guys doing that mod to their jeeps. the 4.2 is the 4 weight model from a yj, and i think the head is from a renix motor. it was recently put together, had good compression, and all the seals were replaced. my questions are these:
are there holes on the 4.2 block for my a/c, alternator, and power steering pump brackets? will my 4.0 water pump fit so i can run the factory dual fan setup, and the serpentine belt? i'm just tryin to get my jeep goin again, because this is by far the nicest xj i've ever had, and i've been having to dd a motorcycle in the icy coldness for the past couple weeks, and i'm not sure my nuts can shrink much more without imploding:
:scared:
thanks ahead, fellas!
