Does anyone know what is the smallest carb I can fit on a 350? Or does anyone have one forsale? Ruben ruben.h.padilla@opbu.xerox.com
The smallest would be a two barrel. Smallest 4 barrel? I would say a 650cfm would be as small as I would go. DV
i agree with dv that that smallest carb would be a 2 barrel. but i for a four barrel you could go as low as a 500 cfm from edelbrock or other carb manufactures, but i would go with a 600cfm is the lowest i would go. cowboy 1961 chevy 1/2 ton shortstep known as sarah (496 big block coming sooner or later)
howziit guys! using the calculator at www.smokemup.com at 85% volumetric efficiency and 70*F, a sbc 355 would need 392cfm to sustain 4500rpm. 480cfm at 5500rpm, and 600cfm at 6875rpm. FWIW, a big block 454 needs 502cfm at 4500rpm, and 600cfm at 5375rpm. BTW, THE PINK LADY had a 750cfm #####. for gas mileage testing, i replaced the carb with a 600cfm Edelbrock...jetted TWO STEPS LEAN, in power and cruise mode. still testing; low-end response is EXCELLENT, but i can FEEL the midrange/high-end power loss. the spark-plugs read brown...and Noooo, this 454 engine hasn't burned out yet. water temp range is 185*-200*F, runs on 87Octane, no pings, no dieseling...but it is a LAZY RAT ENGINE.}> }> }>
