hosie Posted June 12 Author Share Posted June 12 I have a 455 long block do you have any idea if this carburetor will be okay or is it just for a 350 short block, any idea? Link to comment Share on other sites More sharing options...
joe_padavano Posted June 13 Share Posted June 13 600 CFM is far too small for a 455. The factory Qjet was 750 CFM. Also, an aftermarket E-brock carb will be calibrated for a Chevy 350. You will need to have the patience and skills to change jets and rods to match your engine's needs. Link to comment Share on other sites More sharing options...
