Hi there, my 65 Belvedere was registered, licensed, and insured through American Family. 447" with -1 heads, roller cam, and Holley 1000cfm HP., 727 with ATI converter,cal tracs, 488 gears. Car weighed 3440 with me in it. That car ran multiple bottom to mid 10s launching off idle and shifting around 7k tops. The car also made several trips to car gatherings in my area once I put a good trans cooler on it.
