hey everyone,
i want to gather some info on swithing a 4 speed to an auto for a 79 bronco. it has a 400 but next summer i am dropping in a 429. is it worth the switch and is c-6 the best auto if so. could use some help. look forward to hearing from you.

That'd be my choice. Hard to beat an auto in the mud and with a big block it'll help lessen driveline shock.
C-6 is probably the toughest auto ever made. I've seen them stand up reliably behind 1500 hp blown alky engines in pretty much stock form(try that with a standard!).
Big block C-6's are getting a little harder to find but prolly not as bad as TH400/205 combos.
Now for the cons...not as much engine braking when going down hills and uh..uh..uh...hmmm, all I can think of.

Oh ya...welcome to the board

thats a pretty vague kwestion, kinda like askin which is better a redhead, er a blonde.....everyones gunna have a different opinion.
_Whats the purpose of the vehicle?
_Which are you more comfortable driving?
_Resale.....(some folks won't consider anything but an auto)
...i'm sure theres a ton more variables but I think #2 is the largest factor.
.
..personally, I love havin 3 peddles, and a stout trouble free unit. If yu decide to do it, I might take that 435 offa yer hands
...
...in my driveway its a split, 4 vehicles with manuals, and 2 with autos.......everything, chevy, ford, dodge, jeep, and toyota.

Hey there,
i was just wondering where ya are located and where ya usually go trucking. I also have a pair of c6's i am not using if you need any parts or pieces.
I am in the middle of converting to the 4 speed. i am running a 78 bronc with a punched out 460. I need to find some peoples to go out with. I can't find any willing up in my country.
