Re: WTB 70 chevelle 2 barrel carb
According to the NHRA Engine Guides for '69 & '70 Chevrolet, these are the correct sizes and specs
'69 & '70 Chevrolet Passenger Car - with 350" SBChevy / 2bbl. Rochester - 2GV Model (divorced choke) with 1.686 is the Throttle Blade Bore ( 1 11/16" ( 1.6875" ) with 1.375 is the Venturi / Bowl Section Bore Size ( 1 3/8" ) (these "Big Venturi" 2bbls, are the one's that all of the dirt racers wanted for years.... sometimes incorrectly referred to as the 500 cfm 2bbl. ) (note the '71 Engine Guide shows the SBChevy 350" - 2bbl. carb had been downsized to the 1 1/4" Venturi) ** NHRA Engine Guides for '71, '72, '73 & '74 Chevrolet's - Document the SBChevy 400" - 2bbl. as having the following carb specs. 1.686 is the Throttle Blade Bore ( 1 1/16" ( 1.6875" ) with only a 1.250 is the Venturi / Bowl Section Bore Size ( 1 1/4" ) Hope this helps!

I may have what you are looking for, i will have to find them in the shop and will get back with you. Ran this combo in a Nova 25 years ago and did very well with it. Will let you know what i find.
