Re: 350 hp 327 carb ?
Depends if you are looking to restore or race that engine.
Restore:
'65 - R2818 Corvette only, R3043 Chevelle only
'66 - R3245, R3367 Corvette only, and R3806( a late replacement carb). The R3367 was also used on 327-300hp engines and should not be that hard to find.
'67 - R3806, R3807, R3810 and R3814. These carbs were used on the 350 rated engine in the Corvettes and the 325 rated engine in Chevelles, since they are the same engine with different ratings. The R3806 and the R3810 were also used on the 327-300hp engine in Corvettes. The R3807 and R3814 are California calibrated carbs. As an additional note of interest, the R3810 and R3814 were originally spec'ed for use on '67 Z28s, but that was nixed before it went into production. And the 396-375hp engine is spec'ed with a variation of this series of smaller carbs with R3811 and R3815 designation, though you will never see them in real life.
Race:
For all years, use the Quick Fuel Part Number SSR-585-1VS; it's readily available new and has metering advantages over the old carbs for race use.
