67 with a 390? R code or something like that??
I thought 68 was first year for 390...

The 390 Thunderbird Engine was available in full size Fords from the early 60s. In 66, you could get the 390 GT engine in either a Mustang GT or Fairlane GT (and the Mercury equivalents).
Ford even offered a solid lifter cam 390 rated at 375 Hp, and a 3 duce version at 401 Hp. 406's (428 block, 390 crank) were also offered in limited quantity). Mercury also offered a 410 (428 crank, 390 block) in some of it's cars.
In 1968, a few year end Mustang GTs had the R code 428 CJ (I had one) and Ford won the NHRA Winter Nationals with that car that year. They are very rare, had the Drag Pack option (mine had 4:30 gears) and engine oil coolers. (About 2,200 made, few survived).
A handful of Mercury Cougars were made with Hydraulic cam (the block had to be drilled) 427s before they also went to 428. No Mustang or Mustang GT-500 Shelby's were ever made with the 427 Ford engine (other than experimental cars). The 427 Ford Engine made a few 66 and 67 AC Cobra's legendary.
390 GT motors were actually VG motors, that were handicapped by horrible exhaust manifolds and a transverse muffler. 390 motors were far more durable than 428s due to being internally balanced (428s are external) and having a shorter stroke, the same stoke is used in 390, 406 and 427.
My 68 390 GT was an absolute animal, in one of the lightest cars that could hold a big block. I NEVER lost a race with it, and I raced EVERYONE. It had an aggressive cam, 800 double pumper Holley, Hooker Headers (and mufflers), TRW double roller timing chain, Ford Steel Shim head gaskets (increased compression 1/2 point), Mallory Photo Cell electronic ignition and a HD oil pump.
