Is 426ci 360 a small block?

Don't that beat all. We didn't have full throttle for the last day on the dyno. Now I'm just going to wonder what may have been, 'cause it's not going back on to see what that little difference may have made.

You must be using SF's hydraulic/water actuator. I ditched that problematic system and went to push/pull cable and haven't looked back. Nice job BTW that is big power to be sure. J.Rob
