CUSTOMER PAYS SHIPPING COSTS
I only buy complete, fully functional, factory original GM TBI cores from 1987-1995 and Marine TBI units. Must be with functional factory original injectors. Those with "aftermarket" injectors will be given much less value. Cores that have broken screws (e.g. 454 IAC), broken pod base, stripped fuel fittings will be given less value. SBC cores that have the air horns non-professionally shaved down are not acceptible as a core. Those cores that are exceptionally clean or dirty may have higher or lower core pricing. Broken IAC screws on the 454 will cause core value to decrease. Broken TPS screws on any TBI will also cause core value to decrease.
Complete Core consists of:
1. Base, blades, shaft, shaft spring/spring, complete pod assembly with regulator cover, fuel fittings, factory original injectors.
SBC & BBC- Base only $25
SBC 5.7L (350)- $45 credit (must have 5235206 or 17084327 injectors)

BBC 7.4L (454)
