Carb cfm with ported heads?
A 410 with box stock Edelbrocks is going to be sub 450HP. Refer to that EngineMasters episode here if you wish. A bigger carb is not the answer here but then again you are not asking the right question. Reading through the thread you would be well served by a 650-not joking. I have flowed them @ 20.4" H20 and they flow right @ 704-708 cfm. You are not pulling NEAR that @ max RPM @ max HP. Considering your gears again I say 650. I'm sure this will ruffle some feathers-J.Rob
