Dual Carburetors

im new to rebuilding vehicles/engines. and i'm half way learning as i go right now. and i was wondering if running dual holley 650cfm 4 brl carbs on a 355 would work, or if its just a dumb idea all together or if it would be a better idea to run a lower cfm. i have searched the forum however i cannot find what i am looking for.

Re: Dual Carburetors

alot depends on how the motor is built . heads ported and polished? cam specs? headers? drag racing? daily driver? highway driver? stop n go?etc etc

Re: Dual Carburetors

one thing to consider is how much time you want to invest in tuning. dual quads require higher rpm's as well as a high duration cam which is a pain in traffic. smaller is better, dual 390's on the c-26 edelbrock intake seem to work well.
