318 build with dyno session

In high school, I had a 2 bbl 318 in my Duster that came out of a '67 Fury. It ran great but of course I couldn't be satisfied and pulled the heads to put on a set of 340 heads and cast iron 4 bbl intake that I had laying around. It ran good even though I killed the compression with those heads. It will be good to see what one can really do with the right compression and all bolt on parts.
