Default 4.6 tuning

What is realistic a HP number to expect from a 98 4.6 SOHC w/ supercharger, long tubes, h pipe and cat back?
I would be happy with 400-450HP. Should I just save up and buy a DOHC someday, or is the SOHC good enough to put some dollars into?

If you make 350 WHP with the stock NPI heads/cams/intake consider yourself lucky.

I have heard of bone stock NPI cars making less than 300 WHP with a blower install. I would guess realistically with 10 PSI you might be making 325 WHP.
