Aww you don't like the AMC 150? (Lol I have a 2.5L Wrangler) I am not sure what kind of gas milage you are looking for but 25+ is out of the question. Before you consider doing anything you need to check with your state on emissions requirements and if they require you to have stock emissions equipment on the vehicle. (Or someone who is willing to turn a blind eye to you and hand out an emissions sticker) Now if you just want to swap it out for the chevy 350 SB then it can be somewhat difficult. If you are going to do this then you need to also change out the transmission. Go with the GM NV4500 because it is literally indestructable. Depending on whether you want fuel injection or carburated things more or less simple. You will need to remove the ECU and all the components and replace it with something suitable to the new 350 SB. Several aftermarket companies sell entire engine management kits for engines. Try JEGS automotive and they can get you a crate 350 SB, engine management system and everything else you need. You will need to obviously change out the motor mounts, radiator, exhaust system and the stock ac compressor (unless you can find a bracket) just to name a few. You might consider a different rear end (dana 44) and a larger fuel tank.
