Around 126 Ford GT-40's were produced during the production life span. During this time a wide variety of engines were used to power the vehicle. The MKI used a 255 cubic-inch Indy 4-cam, a 289 and 302 small block. The 289 was by far the most popular, producing between 380 and 400 horsepower. When the MKI returned during the 1968 and 1969 season it was outfitted with a 351 cubic-inch Windsor engine. The MKII came equipped with a 427 cubic-inch NASCAR engine. The third generation, the MK-III, had 289 cubic-inch engines. The final version, the MK-IV all were given 427 cubic-inch power-plants.

and some more info...
Thats a pretty tough question to answer, because it depends as little upon what you call a GT40, and also a number of cars appeared in different guises.... but....
There were 12 of the original GT's... numbered GT/101 to GT/112 (are these a 40 or not?)
Then there were 85 MkI's from 1001 to 1085, and 8 cars with no chassis number, which were later allocated 1086 and 1108 to 1114.
A number of the original GT's received body changes to look like MkI's
There were also 2 cars built by Alan Mann racing, given numbers AM.GT40.1 and AM.GT40.2
The GT40 Mk2 is a little more complicated...
FAV built 2, GT/106 and GT/107, and then changed the designation to Mk2A. They built 8 Mk2A's in '66, and then rebuilt 5 of them as Mk2B's in '67. They also supplied 3 Mk2B's to Alan Mann racing, which never had a Ford Chassis number, but were allocated XGT1 to 3.
Only 7 Mk3's were built GT40M3/1101 to 1107
Then the Mk4...also refered to as the J-Car
12 of these were built, J-1 thru J-12
There are also a few close relatives..
3 MkI chassis were built, and converted into M1's numbered M/10001 to 10003
And finally...
the Mk5.... all the spare parts, incomplete chassis' etc were sold to JW Automotive, who used them to build the Mk5...
There is also of course the Holman & Moody...
H&M built and prepared some of the Shelby 40's, and were given license to produce cars carrying the GT40 Moniker.... 'real' 40?... depends upon your view...
So.. hope that answers your question.... complex isn't it!
