shifting shuts my car off

Naw it should fit in one of the priority flat rate boxes. About $10.50 to ship. If I remember right the carbs he had were Holley's not Carters. I haven't had any experience with them so I don't know if one is better than the other. I have only worked on v8's and on them the old Carters were nearly indestructible. Holley's are good too but not as trouble free as the old Carters were.
