Reply to "multiple carb applications"

As far as aircleaners, first, I'd fabricate an aluminum heat shield around your IDA Webers similar to that used in GT-40s. Airflow in the Pantera rear section is up from under the car, sweeping past the headers.180 degree headers dump an enormous ampount of heat into the airstream, right about where the carbs suck in. Once you have a shield built, then some decent K&Ns or paper cleaner will work fine. Another problem with multiple Webers is, keeping the sheer volume of trying to keep four big hungry fuel bowls full is about all the stock fuel pump can accoplish. All the Weber manuals say to reduce pressure for their carbs, but my experience shows that most regulators on a stock Ford (or Chevy) pump reduces flow, not pressure, so they act as a rev-limiter.
