This ought to be a nice setup! Don't be too quick to sell that trans, unless you have a later one with a slip yoke type tailshaft. You need a trans that came out from behind a big block. Next you need a swap kit from Mopar Performance, I think it includes a rear sump oilpan, pickup, dipstick, and some mounts. You may be able to find a big block truck in a salvage yard for these items, 72-78, but don't count on it! Trans crossmember should be the same. Now you need exhaust. Headers are made by several manufacturers, or you will need center dump exhaust manifolds from 72-78, I've seen magnum exhaust manifolds used, but the frame must be knotched thus weakening it. Three or four row radiator. make sure the inlet is on the correct side for your 413.The rest is just minor stuff, two last things to think of 1, the big block is quite a bit heavier I.E. springs, brakes and such. 2 this engine has an advertised compression ratio of 10.10 to 1. Okay for a toy but I wouldn't want to tow with it. Good Luck!
