Keeping the Carbs
To choose the right power valve for your engine, you'll first need to measure the vacuum at idle. With an automatic transmission, you should measure the vacuum with the transmission in drive, the engine idling warm, and the parking brake set. Obviously, manual transmissions should be in neutral. After you've read the engine vacuum, install a power valve that is at least two or three full steps down from your reading. As an example, if your engine vacuum reading is 12", you should install at least a 9.5- or 8.5-power valve or even a 6.5 as supplied with most kits. View Related Article
