Journey to the Dark Side

[Stefano]

The 427s and 428s do fit between the stock shock towers of the'67-'68 Mustangs. It is the Boss 429s which were very wide at approx. 30 inches which needed a bit of help getting shoe horned into the 1969-1970 cars.

Clill,
I believe that your Shelby is the only 1967 Documented to have had a 427 installed by Shelby American, Inc.

I checked the Shelby World Registry which has info on Super Snake on page 615. All the Shelby invoives for the 1967 Cars were found and they show a total of only three cars with 427 engines and only two of the three with the GT40 spec 427 ever produced by Shelby American. Inc.
