Decent hp mods to my 1998

I've seen in either 5.0 mustang or MM&FF that the stock intake can be ported for a good 40hp.

I'm atleast going to try and hit atleast 350bhp without removing/replacing the heads. Not really looking for massive gains yet, just some more umph. Plans are 4.10's, Steeda Pulleys, JLT RAI, Accufab Single Blade, maybe a URP catted X and possibly porting the intake.

I have no idea what gains to expect cause I use to be a 2v guy (PI'd) and yeah my GT was faster than my cobra.

Can you guys help me out?

3kgt95 - 2004 PI headswap w/ .035 gap, Custom ported plenum, 75mm tb, gutted h-pipe, mac cat-back, custom cai w/ k&n, predator, trans-cooler, 3.73's
