I stand partially corrected...the LS-7 is a big block...but the LS7 is a 505hp small block found in the Corvette Z06, not the ZR-1.

check it out...

There's a difference between LS7 and LS-7? Wow. And the ZR-1 does have the LS-9, which is blown, right? I cant chase that link right now.

The ZR1 has an LS9 engine which is blown. The LS7 is the largest displacement small block that GM made squeezing 7.0 liters into a small frame. The LS9 is a 6.2 liter engine that GM managed to squeeze over 100hp per liter.

would love to turn my car over to these guys...and they are pretty much local...just west of Richmond about 10 min drive...check out the gallery
