I saw my name under the list of low 13 second Mach's with very little mods and thought I'd chime in. I ran a 13.08 @ 108.63 with a 1.973 60'. You forgot to mention that I have flow master mufflers along with my X pipe and
K&N drop in air filter, but the flow master's didn't do crap anyway.
The ET isn't in the 12's, but the mph is still pretty high. I don't think there's any argument that a trap speed of 108.63 could easily be in the 12's with more traction. My 60' is good, but I still spin all over the place going into 2nd gear... so bad that I've almost hit the wall going into it oh about 3 times now. I don't see any minimally modded GT's getting that kind of trap speed on this forum. Trap speed is a good measurement for ET potential.
This is my first stick shift as well as first RWD vehicle and I'm still learning. Still I don't think 13.08 is all that bad.
.6 tenths is more than you think. That's not exactly 'hanging' with a car.
Here's me beating a bone stock Mach by 1.5 tenths of a second, but because of the reaction time I crossed the finish line about .5635 seconds before him. You can't tell in the picture, but I'm winning by at least 3 car lengths
Here's the timeslip from that race:
It's the time slip on the right. Ignore the one on the left. The one on the left was the first run of the day and I spun all over the place; the 60' tells the story.
And here's a timeslip of me vs. an '01 Cobra with almost the exact same mods I have:
The timeslip for me vs. the yellow Mach was the yellow Mach driver's very first run ever. Later he had a second run of 13.15x @ 105.82 mph. Not too shabby considering it was his first time at the track and he was bone stock!
If you think the time slips might have been doctored for whatever reason or maybe our cars aren't close to stock, take a look at this:

I'm Robert Braddock Junior under the factory stock table and the yellow Mach 1 driver is Kevin Hassler right under me. I forgot to put Mach 1 under model for the registration.
Saying a minimally modded GT can take a Mach 1 is rice boy talk. "I can take a '72 honda Civic and put 8 grand into it and have it run low 10's and spend 15 grand less than you did for your Mach 1!". You're saying basically the same thing.
This is how it is: If you put the same mods and the Mach 1 as you do on the GT, the Mach will always win. Same thing with a Cobra vs a Mach 1, mods being equal the Cobra will always beat the Mach 1. Although you could be a smartass and make the Cobra and Mach 1 both have a Kenne Bell supercharger and the Mach 1 will win, but let's not get into that.
And about LS1's
My friend has an '01 Z28 with all those free mods, full exhuast 4.10 (or maybe it's 4.11) gears, K&N drop in air filter and U/D pullies and we run side by side ALL the way. I also beat a stock appearing 35th anniversary SS Camaro TOP end on a highway up to 150 mph. That's where the LS1 is SUPPOSED to be strongest. I've beaten countless 'vettes also. Most of them I've raced were faster than the F-bodies which I've also beaten. I have another friend with a Trans Am who's mostly stock running 13.5's at the SAME track as I do. The LT1's are even worse; they're a joke.
But to get back to the original question that was asked for this thread. You cannot make your GT engine the same as the Mach 1 engine. The engines are COMPLETELY different and share no parts. The Mach 1 even has a different block. You can obviously get the same power with mods, though.
Just thought I'd post some evidence of my own. Thanks for reading.
I've got no beef with the Mustang GT owners. If they weren't so successful, my car would have never been built.
