I know the spedo goes up to 160MPH but can an unmodified I6 in the 280 really do it without killing yourself? I got my '75 Automatic (black) up to 126MPH before s&^%ting my pants, and coming back down to 40 MPH with drum brakes wasn't fun anymore. My '78 280 4-speed (white), I only got up to 112 MPH before I thought the door panels were going to get sucked off (bad mirrors), but RPMs were only at 4200, so I had room if the areodynamics were right (same road btw). Now I've gone to the "insta-classic" and driving a 2026 Heritage Twin Turbo, and didn't get nervous until it quickly got up to 121 MPH (Except for the police possibility of course), the new one still feels like the old 280 inside with all the happy tech, and OMG 400 HP will take your breath away. So I'm curious, what's the fastest that you've got your Z up to on public roads before getting nervous? please include year, trans, stock or custom? Also include your top speed around a 20 MPH clover leaf... (62 in the 280s and 74 MPH (barely held) in the Heritage TT, btw).
