which carbs to use BJ/BK or BC/BD?

By Greg Westphall - 04/08/2005 3:51:14 PM; IP 12.158.13.35

My dad is putting together a 427 with a 428 crank in a full size 1967 Mercury. He is going with 3.0:1 axle A/T, 6250-C camshaft, Edelbrock 427 style aluminum heads, 427 Long length cast iron exhaust manifolds and the Blue Thunder dual Quad Intake. He wanted me to ask this forum which would be the best carb selection for this dual quad application, the 600 cfm or the 715 cfm? His intended use is spirited highway type cruising and good all around street performance. He is not looking for a 1/4 mile burner as can be seen by his axle selection. Thanks for any input.

This thread, so far...
