It is a lot smoother but those top rows should be around 34 degrees for a big block with aluminum heads. The engine is going to be up there in the top rows at WOT. Where the engine is at WOT depends on your barometric pressure so you need to think about that but you also need to think about what happens if you drive the car somewhere else. For example, we were on the dyno today with a BB Mopar using EFI and at WOT the engine was right at 100 kpa. Barometric pressure was 102 kpa outside but inside the throttle body it was 100 kpa. So 2 kpa of pressure drop across the throttle body. On your table the timing would've been very retarded at 100 kpa. You would be giving up a ton of power with that tune.
