Default Fastest N/A 4.6?

I know the blown Cobras are fast and that nitrous can really wake up the the Mach 1, but who has a pretty fast N/A 4.6L Mustang, either a SOHC GT or a DOHC Mach 1? Just curious as to the potential of these motors.
Sorry if this is the wrong forum.

Code3GT has a pretty fast NA 4.6

From my understanding there is some serious money into the motor and he's running mid 12's NA....

To be honest, without very deep pockets a fast NA 4.6 isn't possible... Atleast no where near the performance per dollar of a push rod motor.

latest isuue of MM&FF had 8 or 9 DOHC 4.6 mach 1's/cobra in the 11's na. There was a 5.4 Liter DOHC cobra that ticked off a 10.03, 540 rwhp out of 5.4 liters na, not bad eh.

I've always seen the Mach 1s and 99-up Cobras as equals to the LS1, and there are bolt-on LS1s in the 11s, cam-only LS1s in the high 10s, and heads and cam LS1s in the low-mid 10s. Surely the Mach 1 and later N/A Cobras can do the same, right?
I'm seriously thinking about getting an 03-04 Mach 1, that's why I'm curious. Don't tell my GM homies.

The fastest non supercharged mustang is the mach1. Suspension mods alone will yield VERY fast 1/4 mile times. Of course the cobra is faster but you cant find them as cheap.

still, there were several 4.6's in the lower 11's.

One mach 1 went 11.44 with stock cams, and 3400 pound race weight.

The fastest 2V 4.6 is Ken Bjonnes old car from MD Motorsports. He ran a 10.83, but it's an all out race car. To make alot of power in a 2V 4.6, you must spend ALOT of $$. I have over $11,000.00 in my motor and it runs mid 12's. But, I have full interior and the only suspension mods are upper/lower CA's and Fox body rear shocks.
