Just got my 12 Port News and I read that the Holley 390cfm is NOT the good choice for my inline 250 Late Chevy? huh? Instead it suggest that a 600/650 is a better choice. What?

Everything I have read says do not overcarburate your motor unless it is pure race.

My street 250 will have mild cam, offy four barrel manifold and some sort of headers, coupled with an HEI ignition. Do I need more carb for this?
CAN Somebody please SPLAIN to me why this carb is not recommended for this engine?
