Tunnel Ram Carbs for 383?

hey JGC-go with the 1.75" headers, 1.625" are too small for big block ports. the holley guy is not going to say use a carter/edelb carb. I say go 500 carter/edelbrock. and yes, mrtech, 2 barrel and 4 barrel carbs are rated different, and was not the center carb on a 340/6 smaller than a 440/6? and I would not dig for any old holleys, if U want to dig for old small stuff carter made 400 afbs
