How many CFM for my 340?
My 67 Dart 340 4 speed is going to get carb replacement. The car has a 6 pack style air scoop on the hood that's got a 16" round cut out for my 14" K&N air filter. Right now the air cleaner is pushed up into air comming in by 2 spacers of about 3" to 4" above the carb. I have a 650 CFM Edelbrock carb on an Edelbrock Performer RPM intake. My 340 has a cam, but I don't know what cam, and it has headers. Can I go with a Edelbrock 750 CFM carb with my 4 speed stick Dart? I'm also going to put a 4 hole 1" thermal spacer under the carb with the change. I read 750 is doable and in 71 the thermoquads were pushing as much as 800 CFM on a factory motor. 750 sounds a bit much for a 340. What's the opinion out there?
