67 - 68 Mustang GT was a 390 and I believe they called it "Cobra Jet".

1968   Cobra Jet          428/335
          Shelby Cobra GT500          428/350
1969   Cobra Jet          428/335

1870   Cobra Jet          428/335
          Cobra Jet          428/370

Was they're a 390 Cobra jet torino in 68/69?

[JimNolan]

From what I've read on the web-sites, there were a number of models that had 428s and 429 Cobra Jet and Super Cobra Jet engines. Nowhere did I find a 390 called a cobra Jet. That doesn't mean there weren't, it just means that I can't find it on the WWW. Jim

Jim,1870 Cobra Jets?That would have made the drive west go alot quicker. lol As long as we're talk'n CJ's,don't forget the 351s.Their sure as heck were 390 police intercepors but no CJs.

CJ (and SCJ) were descriptions of the High Output 68/70 FE 428, the 70/71 429 385 Series and the 71/74 351C.

The HI-PO 390 66/68 (320/335HP) was referred to as the GT. The 1968 427CI/390HP engine (W-Code) was only available in the 68 COUGAR GT-E and was dropped with the introduction of the 428CJ (APR 68).
