Shelby only offered a factory installed Paxton supercharger option for the GT350 in 1966 and 1967. It was a very expensive (and relatively unknown) option so few were actually built. How few? 11 in 1966 and “35” in 1967. I offer the number of 35 in asterisks since opinions vary on how many were actually built. The original 1967 Shelby American factory invoices state 28 cars. Some Shelby experts state the number was actually 19, while others say 35 were produced. AllI know is that I have been tracking Shelby Mustangs for decades and I can count the number of real factory supercharged cars I have seen on one hand- with fingers left over.
And just how expensive was the factory installed Paxton option? About $700. Compare that to the $200 the GT500 option cost and you can see why so few supercharged GT350s were built.
Production numbers (and superchargers) aside, I like the 67 GT350 vs. the GT500 from a performance standpoint. For one it is almost 300 Ibs lighter (over the front wheels no less) and the K Gode 289 is a more eager performer than the 428 PI. And, there is only one carb to leak fuel and it’s a lot easier to get to the spark plugs! I also like the production numbers for the GT350 more:
1967 GT500 total production: 2,044
1967 GT350 total production: 1135
So if you’re going to have a 1967 GT350 the ultimate is obviously a factory Supercharged one- especially if you are a Paxton junkie like me!
The S/G GT350 in our collection is #2308, a well known and very correct factory Paxton car with its original drivetrain and, perhaps even more rare, its original Paxton blower, pressure box, carburetor, and Paxton gauges. It was. restored under the guidance of acknowledged 1967 Shelby experts and has won numerous high level SAAC and MCA shows.
