    carburator upgrade Question

     



    Hi there Hot rod guys,

    I got a general question about a carburator upgrade on my Chevy 1986 350M engine being used in a Motorhome GM's VAN G30 dually application with a Turbo 400 tranny and dual exhaust.s All air pumps and emission garbage have been removed.

    Currently, it has GM electric choked Quadrajunk factory original carb (750cfm I think) on it now but I want to go with a new Modern carb and according to my numerical calculations and my normal cruise RPMS at 3000, could I put an Edelbrock 1406 or a Holly 4160 600 cfm carb with electric choke on it? My top RPMs would never be over 4000 and I cruise mostly at 3000 RPMS give or take. What new carb size would you replace the Quadrajunk with?

    This should be an easy question for a motorhead.


    Jeff
