Where's the Wow?

Those adapters are garbage, run the carb style that matches the intake or else get a different carb, or intake lol. My buddy had a '73 B200 van with a 360 4-bbl, previous owner threw a 1406 Edelbrock on there with an adapter for it to fit the factory TQ iron intake and it ran OK. We swapped on a Performer intake with the dual square/spread bore pattern which matched up to the carb perfectly, added a 1" plastic 4-hole spacer to help with heat insulation and boost torque and response a bit... Ran much better overall.
