Shotts,
Didn't mean to offend any 100 owners out there and sorry if I did. You are correct in assuming that I have no experience with the 100 series Cruiser and I am sure that is a VERY capable rig. Whether it is superior to the 80 series is largely a matter of opinion. Personally, I prefer a solid front axle with a factory locker, and an Inline 6, but that is just for me, and I do not wish to influence anyone towards my personal taste.
I have had V8's before, but there were all domestic engines (made by the big 3). In my opinion, they were not great motors, largely because my experience with them wasn't great. My cruiser with 120,000 miles runs flawless, something I couldn't say for ANY V8 I have had personal experience with. And I don't think it's a US vs. Japanese engineering thing either. My uncle has a Ford with the 300 Inline 6 and he has 325,000 miles on his truck and it runs great (and the engine has never been rebuilt), which is saying a LOT for a Ford product made in the late 80's.
I am not a mechanical engineer by any stretch of the imagination, but I think that the inherent balancing issues mentioned by others in previous posts show scientifically that an inline 6 (in theory at least) has a slight design edge over a V8.
Not looking to start a war or hijack a thread. Just my .02. Hopefully someday I will get to test drive the 100 series and change my opinion.
