First time I saw Hubert Platt run a '68 Mustang fastback with Tunnel Port, he had the track to himself. That mustang jumped two feet sideways on every gear change just like that '55. Good thing he had the track to himself, he was all over it until he got the car sorted out for time trials. That '55 would be solid in the 8's with a good C-4. Joe-JDC
