need advice: 440 in a Duster
If you have the 440 and want a ton of torque and a real monster go for it! But as all mentioned above it needs to have the whole package. Especially the brakes and suspension that almost always get over looked.
Even if you went with a stroker small block it would be a monster too, but either way it is a bunch of $$$ but will be really sweet if done the correct way!
I would do it....
