Common Engine Measurments
September 2008
These are not set numbers, and shouldn't be relied on for fabrication or tight tolerance planning. Be sure to get the measurements off your actual motor for this, due to changes throughout production years and different additions / accessories you may use. This is more for comparison than anything, and possibly a starting point for planning. Unless noted, height is from the oil pan to the top of the air cleaner and with is from the outide of the stock exhaust manifolds.
