That's why I'm looking at the aluminum block. The wife is asking me if I want to go Hemi with it, but I'm really liking the idea of doing the RB for some reason. But like you said, the RB for power with all the weight of a fully assembled slant six on the nose! After that it's a matter of finding balance.
I'm knawing at the bit to start a build thread on here, but the wife and I have decided that Grandpa's truck comes first. It'll take less money, needs less work, and the usefulness of having another truck, especially one with a full 8' box, is just too important. Besides, Pop's 68yo now, and it was his dad's truck, so it would mean a lot to have it back in the fold and Pop could drive it again.
