View Full Version : Another V8 Swap Thread

November 18th, 2017, 20:40
I have a '98 auto that I am going to do a GM V8/manual trans swap to and need some input.

My big concern is budget and transmission options. I know I can swap to an AX-15 or NV3550 without issues but I found a few Silverado 1500's with the 4.8, NV3500 and NP241 for pretty cheap. Is the Silverado drivetrain a viable option since all of these components are supposedly very similar to the OEM XJ drivetrain?

the silverado powertrain is stronger than XJs. the 241 is stronger than jeep's 231 and the nv3500 is stronger than ax15. I would swap the whole powertrain.
