I have a 73 fj40 with a sbc 305 with the stock 3 spd tranny and xfer. I have found a sm465 and np205 for $400. I would like to do the swap, but what else do I need to know and is it worth it? Since I can't sell the darn thing I guess I will dump some more money in it to make it the way I want it. Any info would be helpful. Thanks in advance.
