back in the 1970's i knew 2 guys in jackson mississpi with 67 gt 500 shelbys and both had 427 med risers in them and those engines were put in by the owners. the 2 cars came from the factory with 390's.
There was one 427 powered GT-500 made in 1967. It was a special deal where Shelby had a 427 installed and called it a Super Snake. It was utilized for some tire testing. It was determined that the cost of the 427 was prohibitive and that Shelby would continue producing and selling GT-500's with 428 engines.
A few other 67 Shelbys came with factory 427's - very small number- but the SAAC is all over them with documentation I think - and as said above no 69's came from Ford with 427's between their shock towers.
[/SIGPIC]67 Fastback GT -- original colour (Frost Turquoise), original 289 A code engine. Pic is of me and the Mustang taken in May of '67, with original F70-14 Wide Ovals. Same car is now restored to "as new" but 3 speed tranny swapped out for 4 speed back in the mid '80's, with tach dash, original Equalock rear, Koni's, Opentracker UCA, LCA, roller perches and idler arm, roller bearing pedal cluster, Cibie headlights, 4100 carb (old 4300 put in storage probably forever)
Back in the 70's I had a 69 GT500 with the 428 and just down the road from me was a guy with an identical GT500 except it was a 70 that had a dealer installed 427. That car surfaced again awhile back, KAR in Columbus Ohio had it.
There were exactly three 67 GT500's made with factory installed 427's. The Supersnake had a NASCAR prepped 427 medium-riser with aluminum heads and is car number 544. The other two were 427's were medium-risers street form. They were car numbers 289 and 1947.
As of the 1997 printing (the most recent) Shelby American World Registry, there were no 68 GT500's produced with factory installed 427's. There is no mention of a factory installed 427 in car number 4280 in the registry. I would be curious to see documentation on that car to make that claim.
According to Kevin Marti, there were no Mustangs built period with a 427. There were however aprox 350 68 Cougars made with the 427 low-riser engine.

my landlord has one of those 68 cougar GT-E cars sitting beside the house here wasting away. no he aint selling it and swears he will fix it up. i dont think he will.
I did some research looking thru some of my old mustang magazines and books, and came across similar readings of very limited number of 67 and 68 mustangs with the 427 in them. I still have not come across anything on a 69 having the 427. I saw this car at a local cruise, maybe he will be there again where I can get some dirt on his car and I will share the info.
in 68.5 the 428 was first offered in the mustang. it was said by ford that the 428 was the engine of choice for the consumer due to it more low end torque than the 427. the 427 was better suited for higher rpm and longer stroke of the 428 had more low end power. the buick GS of the day was a powerhouse on the street cause it had lots a low end. the 427 was primarly designed for stock car racing. the 428 mustang was fords answer to the bb camaros. in 1967 there was a monster movie called GAMERA but i thought they wuz talkin bout the new chebby sports car !
