Help on dating the engine and which carburettor would suit please as looks like it has now a truck carb (Quadrajet) with ECM control which this car doesn't have!! A suitable replacement Quadrajet to source in UK or alternative manufacturer (e.g Holley) to fit the stock Rochester headers?
Thanks
Cannt see how a ECM carb would work with no ECM.
What is the number of the carburetor?
Rochester never made headers, do you mean intake manifold?
Thanks. The number of the carburetor is very faint and rubbed. Pic attached. Possibly 17082043 if its the same as the stamp on the other side???? Yes, I mean a carb to fit the stock intake manifold.
The faded number in your third picture going vertically up the side is the typical location of the number.
Holley makes a replacement for the Quadrajet in the 4175 series of carburetors. Two examples below.

I think the 80555C should suit as there are no emission considerations here in the UK for a 40 year old car. I assume it should be a straight swap and bolt on hopefully, even though I don't know the exact year of manufacture of the engine. I can source this carb from Amazon UK, at a cheaper price than US+shipping+taxes I think! . I'm just wondering whether I will need a Chevy specific throttle cable bracket and a fast idle selenoid or can use the existing off the Q-jet?
Hard to say about the throttle bracket, looks like it might fit.
