I have 440 with 11 to 1 compression, stage 1 solid lifter cam with factory 413 dual quad set up.. I want to replace that set up with the edlebrock ch28 or offenhauser 5206. Both are dual quad intakes. Any feedback on them will be appreciated. thanks.

this is what i run around on. ch28 with two 600's. smooth power, very low maintenance.

We run a CH28 with 2 Eddy 600s street strip. Been 11.28 in a 65 Belvedere street car.

I would use a dual plane, not a single plane intake unless you run both carbs. using one to one linkage, not progressive
Progressive will work fine on the dual plane intakes

thank you
