I'm currently adapting a rack of four 36mm carbs to a 1.6L (97.64 ci) 4 cylinder engine. I'm trying to figure out how to calculate the proper intake runner length to use. This is to be a zippy daily driver, not an 1/8th mile drag car. I've found information on "Independant Throttle Bodies" length calculations for fuel injected systems, but this involves a plenum and does not seem relevant. Any help would be much appreciated.
