360 Carb input

I'm running a mechanical 6 pack, a true 1,100 cfm setup with three accelerator pumps dumping at once without a bog on my 400 hp 360 !! 4 speeds are less forgiving with a big carb than a auto especially a auto with even a mild stall converter. That said with the 4 speed I would go with a 650dp, you may loose a few up top but idle to 4,500 should make the car rev quicker.
