Smile 1988 Mustang GT vs. 1965 or 1966 Shelby GT-350

Is it true that the 1988 Mustang GT is a faster car off the line than the old Shelby GT-350 Mustang?

The cars mentioned are pretty close in hp and total weight of the car. The car that will be the quickest of the line is going to be the one with steeper rear end gears.

Ford replaced the 3.08's in the 88 to 3.55's.
Don't know what the Shelby came with from factory?
Top end would go to the newer 88 with the VR tires up to 149MPH.

On paper they seem to be close in HP, but they changed the methods of rating HP. I forget exactly what was changed, but older cars seem to have more HP then newer ones, but that is due to that change. But yes 88 GT is just a bit quicker.

93 triple white Limited Edition. 17" Cobra "R"s, Cobra "R" hood, 180* thermo, Steeda Tri-Axe, white faced gauges, Phantom monster tach, 73mm calipers, with slotted fronts rotors, all Alpine stereo equipment, so, still stock (for now)...

I think the 88 will hold the road a little better too. The old ones probably made a little more HP, but couldn't transfer it as well.

The suspension on the older cars allow a lot of body roll and can't control the weight transfer from back to front or side to side as well.

Are you talking about a completely stock '88 GT? If so, my vote would go to the 65/66 GT350. Those cars were rated at 306HP and were lighter than the '88. Especially the '65 (2800 pounds). The '65 did not have a rear seat while the '66 did. 0-60 was about 6.5 with a 14.9 quarter mile. Top speed was around 125. Yes, the '88 would take it top end, but the origianal poster's question was which was quicker off the line.

Isn't the 88 GT a 6.0 second car from 0-60?

The handling or wet weather driving in the fox body is down right scary and dangerous. If it is worse on those older Stangs I would hate to drive one of those in the rain.

Then it is like everything else stock for stock because the 88 GT is factory stock condition that the newer cars of today are better in every performance category over the older 60's cars. Better comfort, gas mileage, handling, braking acceleration, top end speed etc.
The only thing that the oldies have is the styling which is personal preference and bad thing is that they are always in need of constant repair since they are so OLD.

I'd say the 88's for sure. The shelby came with 306hp in the old gross rating not the newer sae net ratings. The amount it would have now (with the newer ratings) would be considerably lower. As for the 3.55 in the 88's I've heard of this as a dealer installed option on some cop cars but never on a stock gt. I'd still give the nod to the newer gt, you ever race a car with the older bias ply tires? And they were skinny as hell too. Very hard to get a car like that off the line.

2.73, 3.08, and 3.27's were the ONLY factory gear options on '79-'93 5.0 Mustangs. Most came with 2.73's or 3.08's.

The Shelby could have had anything from a 3.00 to 4.11's. Most ranged from 3.50's-4.11's.

The only real advantage the fox body has is an extra gear in the T5.
With a decent driver, the GT350 owns you from 1st thru 4th gear.

Shift in to 5th, and the fox will keep going while the Shelby runs out of steam.
