There are some differences in the combo's. The 352 is now rated at at 312hp for the auto. The 352 has a bigger intake valve, 2.06 vs. 2.02 for the 363. The 352 has 11 less ci, with a 4.06 bore vs. the 363 4.125. All other specs and parts are them same.

On its face the 352 looks to be better at 312hp vs. 330hp for the 363, but I can't tell you why it was rated at 330. I can only guess it was a consensus between NHRA and Ford Racing.

I think it is still a good combo even at 330. The valve size to me is a wash because of the bigger bore, you should get better flow into the cylinders with the less shrouding. I also think it might be a better choice at the present time because there are none out there, you would be able to control future horse power increases.
