9000 RPM 150MPH 1960 slant six

The "Sister" car to this one is the Asimmetrica. Also based on a 1960 Valiant, the 124,086th 1960 car built at Hamtramck. It too had a 170 with Hyper Pak components. The 170's were used because of the low hood line that Exner wanted. A 225 was too tall. So it could have gotten another Daytona engine. As far as the 9000 RPM, that is incorrect of course. The XNR has an 8000 RPM tach and the 170 engines were run to 7500 RPM on the dyno. Most people who don't know slants are not aware that they will run high RPM.
