New rules taking effect for the 1966 season dictated that at least 50 examples had to be made to run the GT competition class. By the end of the 1965, specification was finalized, and production versions of the GT40s began with chassis GT40P/1000.

This was a major step for a program which had produced 12 cars of varying specification in 1964 and 1965 with limited results. Mid-1965 production began on series of race and road GT40s from Ford Advanced Vehicles in Slough, England from a finalized tub-chassis design.

Ford changed little for their road-going orders, handing over keys to Le Mans-ready cars for diminutive street use.

Under the large clamshell hood, the production GT40 used the Ford Fairlane V8 which was first installed by Shelby American. For the road, Ford supplied 335 bhp, in competition trim, with a lighter flywheel and no mufflers, this engine produced 380 bhp.

The interior is where Ford Advanced vehicles changed the road cars the most. As one would guess more interior trim, pockets and sound deadening where added in the mix. Further amenities included a heater, a radio and glass windscreens.

In total, 87 production GT40s were made from chassis GT40P/1000 to GT40P/1086. Around 30 of these were delivered with full interiors and wire wheels for use on the road.
