i have the oppotunity to pick up a 77 2wd 150 with a 351 and im guessing a c6, i havent looked at the truck yet to know. i want the moter and tranny for an early bronco project, but i dont know about the feasability of using the c6, especially not having a t-case attached. i havent seen any information on the c6 swap. im wondering if i should just take the moter and part the truck out and look for a c6 or c4 with a t case attached. still in the early stages of this so im just looking at some options. if anyone has info on using a c6 in an eb, and what type of problems i can expect, i would be eternally gratefull to you, my bronco brother!<br><br>billybroncojr<br><a href=http://www.broncoadventures.homestead.com target=new>http://www.broncoadventures.homestead.com</a>

I'm not sure about transfer case fitment. I think you would need a C6 with the case(to be a matched set). You could use the 2whldrive tranney but you would need a output shaft out of a C6 that was out of a 4whldrive and the adapter that's between them and I don't know if there were ever any C6's with a dana 20(might check advanced adapters for an adapter)unless you want a different transfer case,maybe an atlas t-case?

The C6 has not historically been a popular mod for early Broncos. It's been done, but I've heard it's a major PITA and requires costly custom fab brackets, linkages, etc.<br><br>A properly built truck C4 should have no problems handling the output of a 351. Also, since C4's came stock in Broncos it should be fairly easy to mate up the t-case, output shaft, clutch, etc. You didn't mention the type of 351 you were considering. I'd advise against the 351C (Cleveland) since it's typically best for high end horsepower rather than low end torque. The 351W (Windsor) is typically stronger at the low end, cheaper to build, and fits better too.<br><br>Or just drop all that silly auto stuff and put in an ultra low NP435 4 speed! :~) That's what I did!<br><br>Hope this helps some.<br><br>Jon Hanna<br><a href=http://www.jonnybronco.com target=new>http://www.jonnybronco.com</a><br><a href=http://www.californiaspecial.com target=new>http://www.californiaspecial.com</a><br><a href=http://www.classiccarbooks.com target=new>http://www.classiccarbooks.com</a>
