    If your not afraid to try then give it a go. And at that price you better grab the YJ.

    There are plenty of write-ups about engine swaps on the internet and a few people on this board that have done it and im sure are willing to help with questions.

      you could buy an entire donor vehicle with a good drive line and just swap everything. then part out/scrap what's left of the donor.

          Novak Conversions has some very good reading on their website. A V-8 will require motor mounts and a new radiator. You will also need an engine to transmission adapter. My choice of engine would be a small block Chevy.

            SBC is the most common swap, lots of parts and info out on the net about how to and such.

              I bought all my parts for a V-8 swap from our host only thing I dont like is the radiator have had cooling issues on the trail of my electric aux fan fails which it seems to alot other then that not to bad to install and the parts fit

              one thing that is not mentioned about a sbcconversion is the oil filter is in a direct line with the d/l so lift it or use a remote oil filter a buddy of mine just did this swap and drained his filter all over the d/ lhe has a 2 inch lift

                I did the V-8 swap on mine several years ago. I you would like the details on mine just PM me and I will give you my phone number. There is nothing like driving a Jeep with 350 horses under the hood.

                    I am running 4.88s w/35s great for the trail suck at 70 4.56 w 35s would be decent for the road this a usefull site http://www.ringpinion.com/Calc_RPM.aspx and if you are going to be running 35s use an 8.8 or a d44 for the rear the 30 in the front will last if you upgrade the axles or dont lock it and are easy on the skinny pedal

                      I have a quick question for yea. What tranny you goin to run? I just bought a 3/4 ton truck with the 350 in it and am thinking of doin the same thing but also doin the axles.

                        I havent figured it out yet ran into alot of twisting on frame and am in the process of having it fixed ,went to a shop .I was in over my head hes also gonna fix the rusted portions hopefully the integritry wont be compromised .I was told that it can be fixed no problem but it looked pretty bad he says cut out bad part and weld in new anyone think this would be unsafe? what i know of welds is if done correct they are strong but i havent done it on a jeep frame .As far as a tranny im open to suggestions .

                          TH350 or TH400 would do good if you want an auto, SM420 or 465 I believe is manual chevy trans that should work with minimal effort, i.e adapters and stuff. Welding if done correctly is just as strong as the parent metal so I would not worry too much about it. You need to swap out the rear axle atleast I would suggest 44's f/r minimum to handle 35s and the 350.

                            picked up 44 already . Got a great deal on it,FREE,well almost had to promise 2 fishing trips to a freind ,with the price of fuel at the marina it mightve been cheaper to by the rear.
