I am putting an ls1 in my full size blazer. It is stock, I am going to run the edelbrock intake with msd ignition system.

Being as it is stock and not for high rpm, what intake would work best. They offer the single plane and the dual plane.

This is my first engine swap of this kind, any suggestion would be great. I am planing on running a 600 cfm edelbrock. Is this enouph?

Thank you for you input
