Out with the old hot rod in with a new one

How did he use cast iron exhaust manifolds with a 440? I thought that was a no-go? And power steering?

I've wanted to build the '73 Duster I have with a 400 like Mopar would have if they had offered a 400 in a Duster of that year. But I've heard that the B motor is just ok with cast iron manifolds and a 440 was impossible.

I wish I could ask him! He built the car about 17 years ago and as I said he wanted to make it look as if the factory built it, I believe the manifolds are off of a B body if I recall. it is very close on the passenger side but it works! Very fun car took it out tonight to the first car meet and had lots of people asking questions about it! LOL. It was pretty cool.
