1998 xj 350 swap
hello all. I am really close to putting a 350 in my 98 xj with the 4.0 and a automatic AW-4 trans. im wanting to keep the trans if I can. are there any adaptors that go from a 350 gen 1 to a AW-4. also motor mounts. advanced adaptors maybe? couldn't really find much on there website for a AW-4 transmission. thanks guys

What I can tell you is that neither Novak or Advance make an AW4 adapter. Novak does, however, make an AX-15 adapter. Why do you want to keep the transmission so bad?

Empty the 88-98 chevy truck np241 is stronger and a driver side drop and bolts right on a 4l60e.But i will give you a heads up unless its a mud bog jeep a carb and off road don't mix well.Its best to have efi even a throttle body injection is better off road.

Carbs aren't bad offroad if you have them setup right. I've had my Jeep at some crazy angles with no problems. I went from a bastardized 2se carb on the 2.8L to a Holley Truck Avenger on the 3.4L, which is designed out of the box for offroad use.

You can go propane or propane/carb hybrid. "Poor man's fuel injection".
See the can of worms you can open once you start modifying stuff.

A stock rebuilt turbo 400 will pretty much be bullet proof up to 500 hp.. with a few hundred bucks more .. you can make it handle anything and everything you will ever throw at it.. you will twist axles before you destroy a turbo 400 that is built to handle it..

If its a off road toy a turbo 400 is best,If you need a overdrive the 4l60e can be built up to handle some insane power.A 4l80e won't fit the stock trans tunnel in the xj with out some cutting and beating.
