But, put a tune on that L88 and the LS6 is gonna see taillights!

HA!
While not an L88, we've had several L72s as well as an LS6 or two...around town, LS6 has more down low which makes it easier to lug around and show off at the drive-in. But in a straight line, they definitely don't spin up the way an L72 does...our L72 and LS6 were set up exactly the same, and while the LS6 made excellent power, it took it a *skoche* longer to do so and couldn't make it as high...I loved my LS6, don't get me wrong...only thing wrong with that car was that every where I went *EVERYONE* had a red w/black stripes '70 LS6 Chevelle...whether it was real or not!
