Edelbrock TR2X big block Chevy tunnel ram with identical Edelbrock 500 cfm Thunder series carburetors. Pulled this running setup off my engine when I went with the blower, not even one year ago. Includes braided steel fuel lines, air cleaners, regulator and spherical ball linkage. Ran great! Bought the carbs brand new, pic of receipt shown. Manifold is a vintage piece. It should be checked for parallel surfaces, I had to run the thick gaskets to make it seal properly. Also, I still have the original boxes the carbs came in plus all the paperwork for them. No need to screw around rebuilding them or chasing down parts. Reg is a brand new one. Meaning, buyer must set it to 4 -5 psi max with a gauge to be correct for these carbs.
