I wouldn't neccessarily go that far based ont the numbers alone.. A number of factors go into the readings, i.e. accuracy of gauge, how many strokes are measured, etc. I have taken the identical engine and tried the same test with a different gauge, battery, etc., and gotten very different results. But what didn't change dramatically between the tests was the "evenness" of the readings between the cylinders, and that is a very important indicator. 300-340 is just over a 10% variance from one cylinder to the other; not great but not horrible either. I would be much more worried if the numbers were high (even fantastic) on some cylinders but significantly lower on others, i.e. 493/485/480/330. How does it drive? Does it lug up hills? Does it smoke? Does it act like a tired engine? - Ron Salmon The Bus Depot, Inc. www.busdepot.com (215) 234-VWVW |
