I have a 440 punched out to a 500 stroker, Forged crank form 440 source, Indy EZ heads and an Edelbrock dual plane intake. I had a Demon 750 but on the engine dyno the carb was defintly too small. We looked at some of the Demon RS series carbs but went with a Braiswell 1050 in the end. I don't have the cams specs handy but it's around 600.

OK my opinion, get an Indy Dual plane. and get the thing port matched with the heads. That should get that skinny Cuda into the 10's as a street reliable car. ( Don't get the Edelbrock manifold since you would have to mill off the heat transfer passages anyay, well depending on which valley pan you buy)
