I have a 302 Cleveland with a spreadbore pattern 4 barrel intake manifold. Are there any issues I need to be aware of if I bolt a Holley 600 squarebore carby on with an adaptor plate ??? ie does it significantly change air/fuel distribution or starve cylinders as some suggest or all just works with no problems. Any info would be very helpful. I guess I am trying to save buying another carby.
