I always wondered how rough is life with Hemi in A-Body... I mean big block is not fun at all but I still am tempted to go Hemi in my Duster.
I recently finshed building 605ci based on Mega block with Indy cnc heads and tunnel ram, also Milodon gear drive on it. Its now topped with 2 King Demons but hoping to soon order 2 custom built 2 circuit Dominators. Plan is to drive the car on the street but also race a little. Before refresh 67 Coronet ran 8:00 with this setup. I have it on the stand now and when I look at the thing, I can't picture it in my Duster, seems wayyyy to big ;-)
Best of luck, great story and great car!
