Quote from: 98SVT - was 06GT on December 04, 2025, 03:16:54 PMALL the "Shelby, Cobra, GT350, GT500" Mustangs since 1967 have been FULLY developed by Ford Motor Company.
The were done by inhouse by Ford Engineers under the guise of several different departments - Shelby Automotive, Motorsports, SVO, SVT.
Yes even the 2006-08 Shelby GTs got changes installed that were developed and produced by Fords engineers.
Don't forget that the coil spring 3000 Cobra chassis was also created on the drawing board of Ford's chassis genius Klaus Arning - who also created the mods for the 65 GT350 chassis.

How did you manage to run regular gas with 13 To one compression ratio?
VTGT500,
About 20 years latter I took advantage of CNC ported Edlebrock heads with JE pistons to suit chamber profile. Also upgraded to Dove shafts and rocker and with a 294S cam. Three days on a SuperFlow dyno tweaking air:fuel and timing on pump gas best we could garner was 483 HP. In the ball park of what's written about the GT40 program.
Why do built FE engines seem to struggle to get much past 1.1 horsepower per cubic inch? 483hp seems awfully low to me for a built motor but I have read similar figures about other motors also. On the dyno, my 302 cubic inch motor with just 9.9 compression, but running 2x4 holley's made four hundred horsepower. Doesn't seem right that a 427, with 125 cubic inches more than my engine made only an extra 83 horsepower.
