i think somthing like this has already been done by Chevy, but what the heck. what if Chevy took a Corvette Z-06 engine and put it in a Silverado? it would be Chevy's answer to Ford's F-150 SVT Lightning and Dodge's Ram SRT-10. the Chevy Silverado Z-06 would be Chevy's performance pickup. but i think somthing like this has been done before, hasnt it?
