I was just curious as to what it would take to make a 96 Cobra make 400whp naturally aspirated. I have BBK longtubes, BBK O/R X pipe, IMRC deleted, and injectors. No idea what power I'm making and I don't have a tune in it. (Yet)

A lot of money.
When you state you have "injectors" but no tune, are you implying you've changed injectors to a different flow rate than stock? If so, you require a tune to adjust AFR and changing injectors will see neglible performance gains on a otherwise stock motor.

I have no idea what size my injectors are. Previous owner said he put them in.
What color are they?
coyote swap? lol yeah its big $ to keep it n/a cheapest easy route would be to find a used newer 4 valve motor out of a 2001 cobra or 2003 mach 1 or cobra being they already come with the better flowing c heads and intake stock, get the intake and heads ported, a nice set of comp cams, along with your bolt ons should make it a 350-380rwhp car. with aggressive cams, and higher compression can break the 400+rwhp mark. otherwise any other route = more $ your current 96 cobra motor with the older b heads and intake flow not as good as the newer updated 2001+ c heads. your current motor prob would be in the 330-350rwhp range even if you ported the heads and put small cams in. now the c head builts ive seen tons with cams and long tubes and ported heads in the 380+rwhp range n/a
your car as it sits now with your mods is prob not even in the 300rwhp range. i would say stock they dyno around 240-260rwhp. your mods are like 20hp -30 tops gain, so your prob at around 260-290rwhp. with a tune maybe 275-300rwhp tops. even with ported heads cams your car might pick up 30-50rwhp at most which wouldnt be any where near 400rwhp. now the c head cars are rated 320hp they dyno around 270rwhp stock with just exaust they seem to be near 300rwhp. so heads ported cam long tubes a c head car picks up a good 50-100hp it would be a 380-400+rwhp car.

Same as everyone else has been saying. You wont make 400whp n/a on a stock or mild b head long block.
mustangmanjeff is pretty spot on with all his assessment, only part where I would disagree is on the porting of the B heads. Dont even waste your time porting B heads unless your are shooting for the moon with your boost levels. These heads flow just fine, their problem is velocity. Porting them is really just not worth the cash.
