Also you need to work on the transmission as the 4L30E won't work with the factory computer so you would have to swap transmissions as well. It can be done as Dan over on 4x4wire swapped one into his amigo but nothing besides an Isuzu 98+ 3.2/3.5 DOHC is a direct swap or even bolt up. All other 60* bellhousing engines require alot of fab work plus trans changes.
Believe or not I was only getting 11.5 MPG with the VX in the end. After 16 weeks and 4 mechanics all we could do was getting it running driveable enough to trade. Over this time I got to drive it very little with significant HP loss and you all would ban me from the forum for stupidity if you knew the amount of money I've thrown at the VX over the laast 4 months. (divides out to 300.00$ a week. . My new truck with the 8.1 is getting almost 14 with the performance Mods it has come with.
