LOL... I'll run those numbers with the factory 360 dished pistons and smog heads. In fact, I was 13.9's at 3450 (3650 at the line) with 2.45's, no headers and the dished piston 360. Again, just trying to see how 66fs did his measuring to basically dog the 360 as such an underperformer. Not challenge him, just understand him.
