I wasn't that far in the RPMs, I got a FMS 160 speedo thinking I would never tap that out, I had 3.45 rear gears then too, and was about 5000 to 5500 5th. Fast enough I tryed to shift to 6th that I didn't have, so just threw it back in 5th and kept it to the floor. Speedo was diffenety past 160 when I looked down. When the LT1 told me later that his stock 150 speedo was tapped, and he was going to shift to 6th right before we had to brake, I knew mine wasn't lying to me then. I had about 10 cars on him too,.. he probley would of caught me cuz I was just about out of gear. I've never gone that fast sence then, scares the crap out of me on such a short strech. lol
