When you say stock do you mean flat top pistons? With 109cc chambers and 5-6cc valve reliefs the compression is actually a little closer to 8-1. Some "stock" big block pistons actually have a small dome, around 10-14cc, if that's the case your compression is around 9.5-1.

The cam is a tad large for 8-1 and about right for 9.5-1 but it is a 454, that's enough cubes to swallow a slightly big cam, even with the lower compression.

I think you'll get 13s at the strip easy, low 13s if the compressions a bit higher than you think. I wish I had a 454 to play with.

Enjoy it man, it sounds like it would be a hoot to drive.
