My Engine: 1985 350 sbc, the motor is completely stock except for a .268 duration cam, double roller timing chain, Edelbrock performer intake manifold, and the carburator listed above.
So is this carburator too big for my motor?
Thanks, Nate

the carb is definitely too big for the engine, however the size of the venturies has nothing to do at all with ease of startup, or idle quality. The carburetor may be at fault for the hard start condition you are experiencing (most likely a misadjusted or inopperative choke or fast idle) if you have money to spend i'd recommend a 550-600cfm carb.
