[QUOTE="ytradio, post: 438877, member: 19779"] From your post it sounds like you are saying that the original engine is a 91 and the new engine that you bought is carbureted. If this is correct then you have a 4.0 and are trying to replace it with a 4.2. If this is correct just changing the intake and distributor aren’t going to work. And I don’t know if the 4.0 system can be made to work on the 4.2. [/QUOTE]
