Tunnel Ram on a 383
Hmmmm so I must have been dreaming when I did this.... 383-400 is a different animal. Remember you are using the same heads as the 440 with less cubes. It makes a difference.
I ran a single 4 tunnel ram with a TQ on my 71 Demon with the HP cast iron exhaust on a 400 and it was a beast. A stock smaller converter with a 727 and gears anywhere from 3.23 to 4.56 and blew many doors off. Run a good X pipe on your exhaust and that will also give you nice low end gains.
