A couple months ago my mom got a used car, Buick Park Avenue with the 231 V6. I've done some research on these engines and the Buick 231/3.8L/3800 is the decendant of the 225 V6 that used to be used in the Jeeps in the 60's. What's intrigued me is how those engines back then were odd-fire motors, and the odd-fire arrangement made them very hard to stall at low engine speeds due to the heavy flywheels needed to smooth them out. So now I'm wondering, if I get an S10 as my next vehicle, I might just swap a pre-85 90-degree Chevy V6 in it, since it's an odd-fire motor too. Who in here has driven vehicles with these odd-fire engines in them? How were they? I've heard they have a pretty good rumble to them with free-flowing exhausts.
