Hi guys , I have a mild 460 BBF with an Offy duel 4 t/r (the one that has a divider in the plenum kinda like a duel plane). The motor has 11 to 1 cr ported heads and the cam is 565 lift 280 dur (232 at .050) and 108 deg lobe center.
I need to make a decision about carbs. A few people have recommended the Holley 450 mech sec, and others say go bigger than that, what do you guys think ?? I do have one Holley 750 vac sec (3310s) and I could pick up another one of those if you think that will work ?
