This is generally not a problem but the parallel linkage C300 dual carb setup could be. Progressive linkage dual carburetor arrangements or engines with single carburetors would be much easier to retrofit closed crankcase systems. Hook a PCV valve into one carburetor of a C300 and there will be a carburetion imbalance that might or might not be fixable with tuning the carbs and linkages. The carburetor balance situation is probably why CA put 300's on the no retrofit list in the '60's. Warren Anderson Sedona,AZ
