What year are you speaking of, if it is a later 80s or early 90s you have a ZF trans, what are you trying to do, swap a ZF for a C-6? Advise the year and what you are trying to do, and we can probaly help

460 5 Speed

alright, you guys are going to have to excuse me, but, I am kind of young. I have a 429 out of a 1971 Mercury Marquis that I am going to rebuild. But, I don't want the original three speed that came with it. i want five speeds for better gas mileage and\or performance. I want to know if any 460 5 speed tranny will connect to a 429 of that year?

You would be better off trading that 429 for a 460. The 429 has around 10:1 compression and will demand premium fuel to run without pinging. Most later model 460s have around 8.5 to 9.0 compression and will run just find on regular, plus the longer stroke gives more "umph" for pulling power. No mater what tranny you get those big block Fords never did get very good mileage. I have run over 700 HP through a C-6 automatic in a drag car and never broke a thing except the high dollar torq-converters. A C-6 with a competition shift kit will outshift any truck-type stick transmission and is much easier on the rest of your drive train.
