Dual Air Meter Units
Bill Thomas Race Cars in the 1960's led the way on light 1800 pound fiberglass race cars with a Corvette drive train. They were probably the most successful at engineering and building dual air meter Rochester fuel injection units that actually ran well.
Typically his units were built with 1963 and 1964 base units. The top plenum lid was discarded and replaced with a machined aluminum base plate. Two like air meters were added without choke housing assemblies. Who needed a choke on a race car anyway?
Many modifications had to be made for functionality including: creation of modified throttle linkage, signal lines were shared, fuel valve modifications etc. Some plenums were left at stock OEM height and others were milled down. Air cleaner assemblies were nothing more than a mere air cleaner adapter with a mesh screen to keep large debris out.
