AW4 mated to a BB Ford?? - Pirate4x4.Com : 4x4 and Off-Road Forum

Somwhat crazy question but I do know the AW4 is capable of big horses (400hp +) and I have a 429 sitting on the garage floor. I've checked Advance adapters and didn't come up with anything.

Anyone thought about this, even remotely? Could I make up an adapter plate myself? I do have reasonable fab skills and access to a full machine shop. I really like my driveline now as it sits.

I am going to venture far enough to say that the 429 will DESTROY an AW4 if you have a moderately heavy foot (and how could you not with a BBF) I have seen stock BBF's tear up the c6's they came with fairly easily. There is a reason very few if any adapters are made for it.

As tough a little tranny as the AW4 is, and assuming you are speaking of a stock one (well, even built it wouldnt matter), but that BBF just has too many torks.
Th400 is the adapter I would be searching for.

The words AW4 and being in the Jeep forum, I have to assume this is going in an XJ or ZJ. Ever put a 350 in one, not easy. I would think the engine bay wouldn't accomodate the BBF.

I'm running the AW4 in a CJ\YJ rig right now and I like the driveline as it sits. Supra guys run big power through the AW4 so I'd like to think the tranny could handle a stock 429 (360HP).

Just something I was curious to hear some opinons about.

I think those trannies in the supras are the 340 series. The AW4 could probably handle small block v8 power (if built for it, not a stock tranny) but no freakin 429. Don't forget, those supras make a ton of horsepower that isn't coming on off idle, it is higher up in the RPM band, easier on the driveline than making a butt load of torque while chugging the motor.

How about a C6.

They may put "big" HP through them, but thats not the same thing as big block torque. I think the torque would kill the AW4 quickly.

Biggest problem with the AW4 trans is heat buildup, and a lot of torque at a slow speed will do that instantly. If you can keep it cool and have decent gearing in the t-case and axles it MIGHT work.

But you should buy my rebuilt TH400 just to be sure.
