Who was it that won that little comparison you poster earlier?
Facts: Just because you say so doesn't make them so.

According to the "facts" your car gets worse fuel economy as a 7 liter Z06 on it's best day.
That being said, being an owner of a Mustang myself I have to inform you that you can count on the Corvette getting better fuel economy, however you can bet that the POS sickly 3 valve on getting much...much worse.
When ford steps up and puts their 5 liter direct injection in, then maybe the GT will be worth a look until then it is a waste of time.
A comment on the old 4.6 motor you had better be joking when you say that. A clarification as to which 4.6 is needed. Yes the 4.6 DOHC Terminator motor did wake up with mods are you comparing that motor or are you talking about the same years 2 valves that consistantly dyno'ed 215 rwhp on Dyno jets.
Here is another fact, I actually praised the car in my first post if you will refer back to it. If anyone is drinking the Koolaid it is you, I have owned/driven many difernent cars not the least of which was your beloved GT-500.
The facts are that the Mustang is behind the times and no manor of putting sticky ass tires on it from the factory changes the fact that when you go to a GT class race you will not see a single car out there with a SRA and if you do it will undoubtedly be a mustang tagging up the rear.
If you love your car, I happy for ya,...hell good on ya. Honestly at your age to have a car that nice is a damn blessing. I wish I could have been so lucky, but I came up the hard way and bought and built all of my cars starting with...you guessed it Mustangs, and guess what I just cancelled my order for a GT-500 mustang.
