Only 36 GT350R’s were made. 100 GT350′s were all by January 1st, 1965, but it’s unclear how many were “R”, racing designated, and how many were just GT350′s. 100 total had to be made by Jan 1, 1965 to qualify as a production model. The “R” code Shelbys are special racing Mustangs equipped with dual S-W electric fuel pumps, baffled steel high-capacity oil pans by Avaid, custom breathers made from steel valve covers, and of course, competition racing seats.

It’s racing pedigree was active from 1965 through 1971. It beat a Yenko Camaro after starting in the last position. The fiberglass hoods cover a sought-after K-code engine, modified with 715-cfm 4-barrel carbs and high-rise intake manifolds.

These Mustangs have glass-pack mufflers at the end of the dual-exhaust which originates in custom tube headers. They have Borg-Warner T-10 four-speed manual trannies in a lightweight aluminum case. To handle all of that beef, they upgraded the suspension and brakes as well. The backseats were all removed to qualify as a racing 2-seater.
