429 and 4 speed auto
I love the old FE motors but the lack of 4 sp auto is a bad deal unless you go after market aboout 2500 for a 4 sp upgrade to the old c 6. Going with with a 429/460 dropin is a good fit relative EZ to do.
I would like to hear from someone who has installed one with a auto O/D. What year O/D unit did you use and any problems you
makin it shift properly?
One of my boys had a 72 that had a tired 460 and a c6. He had the c6 rebuilt w/shift kit and rebuilt a 70 Merc 429 dropped in w/ duals. That truck would run up a steep hill quicker that most going down one. He still wishes he had it.
Keep her between the ditches and the shiny side up.

Od trannies for the 385 series engines are pricy. I'm installing a 460 c-6 into a 64 f-100 short bed. I'm using the 2.78 rear pumpkin from the 71 Lincoln M-3 that supplied the engine/tranny. The car got 14 mpg. The truck weighting 1 ton less than the car schould get at least 16 to 17 if I can keep my foot out of the carb.
Good luck on your swap
