    Welcomd to the site! I'm sure some of the mechanical types will be able to help you out. My son has an '89 V6 w/auto and 320K miles on it and a 350 would sure do it some good. Good luck!

    Welcome to the site. The engine bolt pattern is the same but the flex plates are different. Also a tired V-6 transmission will not hold up behind a V-8. The V-6 transmission has less clutch plates and runs on lower line pressure. The last thing you want to do is put a fresh V-8 in front of a tired worn out V-6 transmission.

    Default will a 4x2 van work?

    here is another question.
    I have found a donor VAN with a 350 coupled to a 4L60e tranny.(price is right)
    Will i be able to use this two wheel drive tranny for a 4x4 by simply swapping over the tranfer case ? Is there a differance between a 4x2 and a 4x4 tranny?

    You will need to take both transmissions completely apart to switch the output shafts. A lot of work IMO. You would be a lot better off finding a 4X4.
