Help id these carbs

7042240

7041540
I need to know the cfm. I need to know carb # for a 76 Riviera. Also need to know a good site to find cfm and other info on quadrajets. We have 6 storage tubs full of carbs.

 

7042240 and 7041540 are 800 cfm Buick 455 carbs. The other is an Olds carb.

Here is a link to help identify the year an make for what you have. http://www.cliffshighperformance.com/tech_carb_ID_2.html

Let me know if you want to sell some.

 

Thanks for the help. I pulled the 7041540 off a 71 Riviera. Is that the original carb?

 

More than likely yes. 7041540 was used on all 1971 455" (non-Stage 1) applications with automatic transmission.

 

Thanks for the info.

 

The quadrajet for 76 455 would be 17056240

 

I had that carb but it has been moved from where I had it. Now I know what to look for. Thank you
