72 LT1 Carb replacement
I need a replacement Carb for my 1972 LT1. Did some research, some sites say I have GM P/N 3999263 Holley #6239 780cfm 4150 series, another says GM P/N 3986196 Holley #R4555A. Any one have a recommendation as to what model Holley to replace it with and where to purchase it from.
Thanks,
Ed

I found that 3999263 is the number for 72. The other number is 1971 big block. Yours cannt be rebuilt?

Thanks for the input. The general consensus I get from knowledgeable car folks is: Keep The Original And Rebuild It. Getting the car sorted out will take some time, but I'm going to enjoy it.
