460 swap

I have an 89 bronco with a 302 and AOD trans. I am planing to swap in a 460. What trans and transfercase combo would I be best off with. I later plan on a straight axle conversion and 44" boggers if I can afford it, so I need a strong setup, and yes I know i will need stronger axles. I was thinking dana 60 front and a 9" or dana 60 rear.

Re: 460 swap

Depends on what you really want as far as the tranny goes. If you like an auto a c6 is supposedly the way to go. I have 39's on my Bronc, and I plan running a 5.70 gear. Because I will be running such a tall gear I want an auto with overdrive...thus the only way to go is art carr. You can check the website out at artcarr.com. I spoke with the reps on the phone and basically they custom build their tranny to your specification with a single shaft (instead of the crappy two piece that Ford put in their aod) and connect your transfer case...then dyno it. However, if you wanted to go manual there is a bunch of options out there (of which I've not researched [img]/wwwthreads_images/icons/tongue.gif[/img])...
Transfer case wise, an Atlas II is the way to go. It's made by Advance Adapters, and it's pretty hard to find a discounted one. I actually talked one of the reps there down a few hundred bucks, though. Another plus about getting a transfer case from them is that the adapter plate to fit whatever tranny you are going to run is included in the cost of the transfer case, and assembled at their factory.
Axle wise dual dana 60's is the way to go. Just to be different, I will be running extensively modified dual 9's. But, it would prob be easier and cheaper for you to run dual 60's.
Hope this helps.

If you wanna put in a 460, you'll need a Big-Block Trans. The cheapest way to go would be to buy a C6 out of something with a 351M or 400M in it (those are both Big Blocks). If you could find a 78 or 79 Bronco or Pickup, it would come with the Big Block C6 and an NP205 Transfer Case. The 205 is Cast Iron and known to be bullet-proof. Note that even if your Bronco has a C6 in it, it's a Small Block C6 (with a different Bolt Pattern on the Bell Housing). It won't bolt-up to a Big Block Engine. I've seen L&L Product's brochure on Big Block Installations into a Bronco. They sell all of the engine swap parts you'll need such as Motor Mounts. Good Luck.
