    ok...i'm looking at doing a 1985 350 swap in place of my 1986 305 in the next coming weeks. i'm buying the oem replacement engine from scoggin dickey http://www.sdpc2000.com/cart.asp?action=prod_detail&catid=130&pid=383 for this and im wondering, other than the new flex plate http://www.sdpc2000.com/cart.asp?action=prod_detail&catid=882&pid=1196 what else will i need to make this swap.

    i already plan on a new water pump, fuel pump, vacuum hoses, belts & dampener. any help would be great as this is only my second time to replace an engine and my first at swapping different engines.

    As far as I remember you don't NEED anything beside the flexplate. If I were you I would replace the computer controlled carb and distributor.

    I did a similar swap in my '84. I was told by a guy at a tranny shop that I needed to replace the torque converter as well. I knew the tranny was due for a rebuild, so I held off for a few months and changed the converter when I did the tranny rebuild. Anyone else ever heard that?

    Understood. If I were you, or if I were me with the chance to do it over I would have put an MSD billet distributor in my truck, and next time the damn carb needs rebuilt I am getting a Jet stage 2. Also if you can nurse the money tree for a little cash I would try and get myself an MSD box for the new 350. It really helps the motor out. It really helped my 300hp crate from GM, and would have helped the stock replacement crate I had alot too.
