No not directly, mounts will have to be made, the 5.4 tranny will also have to be used, so hardware will have to be manufactured for that, then there is all of the electronics that you will have to put on the 1990 truck, not going to be easy, everything will be a custom build with a lot of trial and error including the exhaust and fuel delivery.

ya I knew I would need the computer for it. OK thanks more work than just rebuilding the 5,8 in it. More power too. Thanks


Yes it would, stick with the 5.8, if you want more ponies you can get some stuff from your local speed shop, or try Summit racing.
