I have seen this response often on this and other threads. You guys need to get real about the differences between a 3.1 and 3.8 normally aspirated-THERE IS NOT A BIG DIFFERENCE IN THESE MOTORS!!!! Essentially a 3.8 is a slightly bored 3.1 that makes 25 horsepower more than my 3.1. How do i know this FACT other than looking at the specs is that I have had 3.8's in a 97 GT, 2004 Impala LS, and currently in a 2001 Buick-Wake up-The 3.8 versus the 3.1 is not like comparing an old chevy straight 6 to a 427 V8-There is very difference between a 3.8 and 3.1 and even a lesser difference in HP!
