Help convince me to go BB in my Duster?

Good to know Doos, are the motorhome 440s worth it? I feel like they are under a lot of load for their mileage.

Also, I've found a couple 440s/trans for around 4-600 but like I said, I'm not currently in the market quite yet.

Unrelated, is the 727 the Auto trans for the 440? Or does it still run a 904?

I'm comfortable with motor home or truck 440s. Best bet is to try and find one you can hear run and make an assessment of the condition. If you can't hear it run you should steer clear of any engines that are outside exposed to the elements. You can also pull a valve cover and have a look. Heavy sludge indicates neglect. Nice and clean or very little sludge is a good sign. Also you will need a different oil pan and pickup tube to drop it into a car. The truck engines have a front sump if I remember right. You need a center sump for a car. The one I sold was ready to rock. I told the buyer if he was going to tear it down he'd be better off looking for a rebuildable core for less money. My guess is with headers it would make about 325,hp with 450 torque. That's enough to have lots of fun.
