Oddball list #'s

Hi Guys, freind of mine has two holley carbs and is trying to decode them. I know Holley has List #'s to ID carbs, yet these numbers don't come up anywhere online. The carbs are off oddball equipment so trying to see if they are any good.

List-6284 and List-7703 are the two carbs he has. I have tried with no luck to find info on these two models, anyone out there that can help??

Here's what I have:

0-6284-1 = 1971 Ford Truck, Super Duty, 477 Engine

0-7703 = 1977 GMC Truck, 427 Engine

Hope this helps.

Have fun.

 

Awesome!! Thanks a bunch...no mention of CFM ratings??...

Thanks again
Tim

 

No. The book I have is strictly a book of part numbers. I can tell you the part # of the rebuild kit and other parts, though. The book is at my house, so I can't get it now.

Have fun.

 

OK, thank you for the help, it is very much appreciated!
