The 4.3 is best for better mileage, and has plenty of daily driving power. But unless you change transmission and transfer case, want ever be able to obtain upper speeds at lower rpm's. I would highly recommend you talk to the guys at Novak adapters. These guys specialize in drivetrain adapters and builds for jeeps. All they do, and know their stuff. Have spent much time on the phone with them. They make an adapter, that will bolt from the 4.3 or chevy V8, that will bolt right up to the T 90 tranny. I am thinking about this route also for daily driving. I just haven't been able bring myself to do this to an all original truck. It's one we all have to decide, if we want an all original truck to putt around town on, or a classic truck, that we can use as a daily driver, that we can actually use? It's a tough choice. These trucks are getting more and more rare in original condition. And I would probably never restomod my truck. Trying to see if I can find a good frame and body somewhere I can build as a restomod for daily driving, and keep my truck in its original condition. But anyone thinking about changing out their motor, would highly recommend thr guys at Novak. They know their stuff, and have been changing motors and components in jeeps for a long time. My perfect setup, would be the 4.3 chevy V6, with an AX15 transmission, and a Dana 300 transfer case. All 3 of these are bomb proof, and Novak offers rebuilt AX15's with upgraded parts, and rebuild all transmissions, and transfer cases with better parts, including the T18, and T90.
