No way is he taking a mid year Vette to 160 on a small block. It would take a little work, some gearing and despite its looks a little aero help. I had a 69 C3 with a small block and although the speedometer went to 160, there was no way the car would have with a mouse motor without some serious work.
Maybe an LT1 with the right gearing or a 427.
My 2014 Stingray would do 185, but not with me driving it. LOL
I just liked to know it that it could. #;^)
