He should be able to go quite a bit faster than 120 lol. My exes dad had a z06 and a zl1. That zl1 was a blast to drive. Never let me drive the vette though.My Silverado will go all the way to 100, but no higher
GM did this because the one-piece drive-shafts aren't safe going much faster
My uncle got the governor taken off of his 2000's Silverado, and now it'll go up to 120. He's got a Camaro ZL1 engine in it though..
I don't know if it still has the factory drive-shaft, and may be geared differently
Same uncle that fixed my truck for me. He used to do auto-salvage. Now he's a railway mechanic
