we have a guy here and I thought he said that the carb guy who rebuilt his had said it was a smaller cfm.If i remember right i'm thinking like 600 or just under? maybe he will chime in and let us know what the cfms were/are on his.But this was off a none turboed v6,and i know you need more with the turbo.
