    Too many to list
    Well it looks like my 3.61L V-6 engine is history after only 91,000 miles. I took such good care of it too. No explanation. I bought it used at 38,000 miles and it had no mechanical issues. Anyway, I've been considering a bigger block in a v8. Chrysler Mopar wants $5800 for a new 3.61. How about a HEMI?? suggestions?

    Do lots of research. I have been looking at many options, i.e. hemi vs LS etc. Them Hemi is a little more expensive. If I do all the work myself, I have gotten the 6.0 LS and 6L80 tranny swap down to under $10k. It is still a lot of money to me. I will run my 3.8 till it dies.

    I have a 2010 JK with 130,000 miles, no problems yet. Have been thinking about repower at some point so I’m very interested in finding out what suggestions are made here. Any comments on diesel?

    Welcome! If you were content with the 3.6 and want to stay on a lower budget look for a good used 3.6 either from CL, wreck yard, remanufactured engine(jasper) or even hemi swap shops who stock low mileage 3.6 for sale (Rubitrux). Get a quote from Rubitrux for either the low-mileage used 3.6 or a Hemi swap.
