To the average person there isn't much of a difference. I feel that it pulls a little harder in the mid range. Will said he was able to add a couple degrees on the 93. Whether there is a true difference or it is just my butt dyno, I guess I'll never know. I'm currently running on the 87 but I can switch at any time as long as I have my laptop(which is almost always.) NA is cool and all and I guess for an NA she boogies pretty good considering it's an H-body. But I purchased a turbo kit a couple weeks ago. So that's happening this Spring most likely.
