Timing curve for my big-cam 451?

I've got a 452" 440 with the mopar 557 mechanical cam mildly ported heads an original M1 intake and a 850 dp and 9.5 cr.
It's been flogged on the dyno after hundreds of passes and thousands of street miles.
You talk about your big cam that's actually to big for a 9.5 motor so not much of a street cam.
