The carb base gasket may not be right for the carb- manifold. You can block off the EGR valve on that model. Your wire going to the HEI ignition should be 10-12 gauge & not use the resistance wire originaly used in the harness.
They say money can't buy happiness. It can buy old Chevy trucks though. Same thing. 1972 Chevy c10 Cheyenne SuperIn the Gallery Forum | | |
