Street/ Strip 383 Build

Put a 499 in the friends Spitzer dragster, makes 803 HP with 499 cubes, breathing thru a mildly prepped set of Indy-1 iron beds. Looks like the engine man did more chamber work, than port cutting. Also, we were told not to try to tune any more power into it, because the stock block won't take what it's making, as is.
