Well, since it's a ZR2 I'd venture it has the 195hp motor, and at least 3.73 gears.
I know that All-Terrains can fit in the ZR2's, but they are pretty tucked up in there. Putting in MT's is very different. They have large knobs on the tire that make them much bigger than the All-Terrains.
And as far as losing power, not too much, although you'll notice it on the hills and such. My friends ZR2 Blazer keeps up pretty good. Well, at least until he hits the speed limiter...
