Edelbrock LD4B - what's the operating range?

Don't know if your wagon has AC - as I recall the arrangement of runners (which are high and which are low) keep you from reinstalling the AC with the LD-4B. This is not true for the Performer, it all fits fine. It is amazing what a difference a manifold, 4bbl and decent dual exhaust make on a 318! Yes there is a Performer intake and an Eddie AFB hiding under there...
