Also-had a 75 Monza with a forged 355. It still had the 2.9? Something rear gears and the yellow Porsche had no idea what happened. 50mph roll on made him look real bad and he wouldn't pull up next to me at the next light. Speedo only went to 85 i think it was,so who knows but it felt real sketchy. Wish I had GPS back then. Posted using the Full Custom H.A.M.B. App!
