Finally swapping cams

I'm finally getting around to changing the cam in my 360.

I'm looking at three different ones, lemme know what you think:

1. Comp XE284H - 284/296, 507/510 lift
2. Mopar 233 - 292/292, 509/509 lift
3. Lunati 60404 - 276/284, 513/533 lift

This is going in a 360 with 9.5:1 compression, X heads, 750HP, headers, etc, etc, etc. Full specs are here: http://www.burwoodboysracing.com/about_the_car.htm

It'll be replacing a Crane 454/480 lift cam. I'm looking to get from the car from the low 12s into the mid to high 11s.

Comments? Suggestions for a different cam?
