I recently purchased a 1973 K-5 (350/350). I'm the third owner and the vehicle is, for the most part, in amazingly stock condition. The previous owner replaced the OEM intake and Q-jet with an Edlebrock square bore carb (#1405) and non-emissions Performer intake. In doing so much of the emmisions equipment was removed (no AIR system, no EGR). The EVAP is still intact but I question it's performance; which leads me to my questions: 1) Can I or should I remove the EVAP? 2) If the lines and canister are removed what mods need to be done to properly vent the gas tank? From what I can tell it's a fairly simple system: one line in from the fuel tank, one line out to the PCV/carb. No emmissions test here in Florida (yet)! Thanks! BTW - Anyone know how to fit tall valve covers under that damn AC compressor bracket?!?
