At the moment I'm leaning to the 60404, although I was curious about the edelbrock cam simply because I'm running the RPM heads and intake and would like the cam to be well matched to those obviously. I'm no cam guru though, so I really don't know if the edelbrock rpm cam is a better match than the lunati. As far as the 770, when Mopar Muscle did a stock 340 build up they put a 800cfm thunder AVS on an otherwise stock 340 and gained 35 hp and 22 ft lbs of torque, with the carb just out of the box; the edelbrock heads will flow better than the stock X's and any of the cams I'm looking at will be more radical than the stocker, so thats how I based my decision for the carb. Lunati recommends a 750 cfm for the 60404 and a 700 for the 60403.
As far as the power brakes go, they're on the car now, but if it doesn't work out I'd much rather convert to manual than short my engine. I've driven manual brakes before, so thats no big deal. I really do like my vehicles to be no frills cars that take more than a little driving skill to handle. In the past I've driven a '56 Austin Healey roadster, set up for vintage racing with its original 1956 162 ci 4 banger putting out over 150 hp, year round on the street (for about 5 years), as well as a '56 ford pickup with a 3 on the tree that I drove in LA for a year (talk about a left leg workout!). The challenger already keeps my dry when it rains, and I doubt the clutch effort will be anywhere near the old ford, so if the idle is on the rough side and I need to heel-toe a little its fine by me, I just want that 340 to be wicked...
