is this an ok combo for a 1971 f600 (360 with C6) and if will work would i have to change out the 2 speed rear end cause of the c6. Any help would be great.

 

it will work , just depends on how you will work the truck ! not the best tranny for towing what the truck was made for 20,000 lbs +- ! and the 2 spd rear will be fine ! if you can put a big tranny cooler on the C6 and a shift kit wont hurt !

 

would you know if the original tranny that bolted up to a 370 bolt up to my 360.

 

Ford offered the C6 in the lighter duty mid 70's C series as a cheap to purchase / economy special. Due to the high first gear / lack of sufficient gears / gear spread to provide a gear for all road speeds, every truck that i have been around has a two speed rear end. Even with the cost of the two speed rear, it was cheaper to purchase a C6 / two speed than the much better, much heavier Allison with more gears / better gear spread option. You get what you pay for I guess in this case.

At the time, the C6 in big trucks had mixed reviews. You dont see them at all nowdays, so I would hazard to guess that most of them have been retired many years ago when there owners got tired of replacing / rebuilding the transmissions. The C6 is tough, but it was never designed to run for miles heavily loaded in second gear, which is where it would fail most often at, especialy if the driver did not use low range on the two speed rear. Definatly pushing the envelope if you are moving more than 15k - 17k.

the 370 uses the same bolt pattern as a 460 , the 360 is totally different as it is a FE engine !

 

thanks guys for the info but since i live in Ca. registering it will cost an arm and a leg so i guess i will have to stick with the smaller trucks. thanks agian.
