I had one and hot rodded sbc 262 V8, wild Hooker headers that were at least three pieces each side, fly eye air cleaner on a 400 sbc carb off a Kingswood Estate and Accel ignition. Turbo Corvair mufflers , you could hear me coming for blocks. It flew but didn't stop too well with those Vega non-finned rotors and heavy V8 up front. . I learned how to do brakes by owning that car. I recall heading up ON HWY 400 on a cottage run and a Corvette wanted to pass me, I pounded my foot to the floor and the little Monza kept door to door with it. Another time a Buick Estate wagon was clicking over at the gas pumps. I offered the owner a boost, he was well dressed businessman on way home form work one cold snowy evening, he sort of chuckled, No son this has a 455 I don't think its got enough juice. I asked him if he wanted to get going or hang around for the CAA. When I popped the hood he said Holy Eff, that thing could power a small town! Needless to say he was underway in short order.
