Help Identifying Weber Carbs
 

Can anyone identify this Weber carb setup, I was told the # 3742580 is a GM #?

They look like pre 1992 carbs as Webber moved their manufacturing from Italy to Spain in 1992.

They look to be from the Can Am period of Aluminum Big Block Chevrolet Racing days. Bill

Thanks for all the help, I will let you know what I find out.

Does it appear to be a BBC manifold Jeff? Hard for me to tell from the pics.

Sorry guys, it is a SB

Is that a grand Sport setup? Sure looks like it !! If so, you hit the jackpot! Those cars rarely change hands, but when they do, they sell for millions.

I searched for an intake setup for years after I found a set of heads.( I posted a pic of my heads and an original motor. )

Only other intake I ever saw was a member here that has an NOS intake, but it needed finish machining. Maybe someone can find that thread .

----When Classic Motors restored GS #1 it was restored with a very special 377 small block and a set of crossram Webers that came right out of the skunkworks at the tech center. This set looks visibly the same. When GS#1 was re-restored more correctly by a guy named Jim Purvis it was done with a big block and 4-barrel. You can see a pic of the car in that livery on the Fram oil filter box (I think), therefore I have no idea where the set of Webers and intake went after that. I was shop manager at Classic during this period and GS#1 was restored off sight so I wasn't real close to what went on with that project. I suppose this set could be that set,,,maybe!....Bill S

If originally installed on grand sport car that is worth $50,000
