250 Hp Corvair powered mid engine vintage formula Atlantic race car we used to set FTD's auto crossing every time out. I remember one time the engine backfired on startup on the start line and the foam in the intake box right behind my head caught fire. I had know idea until the safety steward doused me with a fire extinguisher. The corvair engine was super tricked out with 11:1 CR. custom built heads with intake tubes running to each cylinder and a 750CFM Quadrajet 4 barrel carb. Car ran on 110 octane race fuel only. The 900 lb car was a rocket. It was touted as the fastest Corvair on the planet. The car was built by Corvair go fast guru Warren Leveque.
