rochester 2bbl, right? 1975 year vehicle, Chevy, with automatic transmission. Its date code is the 268th day of 1974 when it was made, and the "OY" referrs to the destination location where it was delivered for installation (I think).
it's probably not a "big bore" 2bbl, it's more like a 1 1/4" or 1 5/16" venturi, run of the mill carb off a car.
It'll get you started, but won't deliver the power that a well built 1 3/8" 2G can.

Hope that helps,
KP

Yes, we do that all the time, where it's legal of course...
If there are no real rules or tech (other than it has to look like a Rochester 2bbl), then we can modify it to flow about 680cfm.

About how much would it cost to build a carb like that? I cant recall what the rules exactly say but i know everyone has them bored. I should say its running on a restricted motor and possible then going to a hobby stock motor. Thanks KP
