I won't run any more DynoSims with a flat tappet cam. Here's a combination of parts for a street/strip motor....
454 bored +0.030". Align hone the main bearing bores. Deck the block at 9.790", registering off the main bearing bore. With the pistons you will be using and a 0.039" head gasket, the squish will be 0.049".
Keith Black #KB257 pistons (pay attention to top ring gap and piston to wall clearance recommendations from the manufacturer).
CompCams 11-450-8 retrofit hydraulic roller cam. Rough idle. Use 2500+ converter.

There are many ways to build a BBC. This is one that I like because the heads work well and don't cost an arm and a leg. You do need to bite the bullet on the roller cam though and be done with it.
