My dad's 49 Cadillac which my brother and I had hot rodded. High compression pistons, 56 heads, Iskanderian cam with solid lifters, high output ignition, tri-power intake manifold, Traction Masters to hold the rear end down and a reworked hydomatic. 19 MPG on the highway and that thing would haul a---, there wasn't much that would stay with it. However, the examiner was NOT impressed but I did pass.
