1961 Pontiac Catalina - Twin Turbo Tarmac Terror
|
In case you couldn't tell, this happens to be a Pontiac 400. The block was bored .030-over and filled with cement to quench whatever vibration-based destruction twin turbos can produce. Builder Marty Palbykin utilizes 0-ring seals between the heads and the grooved block to cope with 23 pounds of boost and an estimated 1,200 horsepower! View Related Article
