Unless there is nitrous involved I seriously doubt that. I agree with adam, I too have seen some rather nice HCI combos that fall short of the 300hp mark. 1.7 roller rockers and a stock cam don't account for much.
revhead347 said:A decent cam isn't that much money anyway. That's the cheapest of the power adders.
The stock cam is pretty decent especially when coupled with 1.7 RR's to add valve lift, and I've seen combos make over 360 flywheel HP on the dyno with the stock cam/1.7 RR's so 300rwhp is definitely possible.
While the cam itself may be inexpensive, you also have to factor in the cost of upgraded valve springs/retainers/keepers unless you order new heads that already have them. Depending on the cam, you may also need to have the pistons flycut to gain piston-to-valve clearance. You also have the additional cost of installing the cam (unless you DIY) plus the possibility of needing to replace cam bearings in the block (which is an engine out job).

I'd expect an SN95 Stang with a T5 and 370 flywheel HP to put down about 320rwhp. With an AODE it would be more like 285rwhp.
Here's an example I got from an old HotRod magazine:
Ford 5.0 V8 EFI
C&L 76mm CAI/MAF kit
Edelbrock 70mm TB
Edelbrock Performer RPM II intake
FRPP 1.7 RR's
Stock cam
Edelbrock Performer RPM II heads
1-5/8" long tube headers
Magnaflow mufflers
FRPP 24lb injectors
Aeromotive fuel pressure regulator
A9L computer with custom chip
372hp @ 6100rpm and 361lbft @ 4700rpm (flywheel) with a 12.5-12.8 A/F ratio
With CompCams XE270HR-12 cam added (PN35-324-8):
388hp @ 6000rpm and 376lbft @ 4900rpm, so that's a mere 16hp/15lbft from the cam swap.

That should actually be pretty close to accurate....those ARE flywheel numbers.....so you're looking at a tad over 300 hp with a t5 and a tad under with an aode. And what stock 5.0 cam is that in the article? It could be a cobra cam...which obviously still isn't a powerhouse....but still good for some extra horses, and who knows how radical that "custom chip" is....just something to think about

Almost forgot ... them hot rod book boys ......
For all we know ... they did that test with no accessories and other little
gain inflating tricks they forgot to tell their readers about
I don't buy into any of those magazines and their tricks. I look at the real world results of peeps here closer to Grady's chart. $h1t I ran a H/C/I manual with trick flows and all supporting parts and only made it to 293rwhp.
No am am with you. For a budget the gt40's or even well ported e7's could do well in my o. If I had to spend the exact same $$ I would go Alums to save 43#. It's just the rwhp claims from mags that I don't completely buy. And I am a bias DD too in terms of driveability definitions. Thats another thread entirely tho.
Here's an example of the difference between engine and chassis dyno numbers with the same engine:
Victory's Engine Dyno
The 306 on that page made 427hp/418lbft on the engine dyno (no PS pump/AC) while on the chassis dyno, it put down 344rwhp/360rwtq and Mark German is the lucky owner:
