1966 Belvedere Test And Tune At US-131 Motorsports Park

Running my dad's 1966 Belvedere at US-131 Motorsports Park - October 22, 2022
The car previously ran 11.70s, however, we had switched to a different carb for this test and tune. The car ran lean all day, in which we finally discovered after several jet changes that we were only getting half throttle with our aftermarket throttle cable. With the old carb and only 3/4 throttle, we ended up running a best of 11.53 at 116 MPH. We hope to make it again this year with the new carburetor and full throttle.
