Wonderful subject and Bob Mullen is a god of Mopar lol.

This whole issue of flow is quite interesting indeed.
David Vizard has used very basic methods for port improvement.
Low Flow is very handy in port work but the consensus seem to like 28 inches.

We are talking 50 years ago with factory cast hipo heads ‘of the day’.
Now we have a head for every occasion and mostly aluminium.

I nearly had the ‘deal of the century’ back in 2005.
A good friend in LA took me to meet Hemi George in Sun Valley.
I was on the hunt for a 426 hemi and he had some for sale.
They were a bit pricey for me so he showed me ‘a builder 426H’.

It was a Bob Mullen experimental hemi in pieces.
George said he has no idea what it’s worth, so I offered $15,000?

He said he would think about it and said “that was the price he wanted too”...

He then decided to build it himself.

It sold for $35,000 oh well, I was very close that time DOH...
