Quoted from jhanley:That's not really true. Almost all 69/70 428 CJ/SCJ were Mach 1's with the stripes. The only difference between the CJ and SCJ was the SCJ had Lemans cap screw rods and special crank. External oil cooler and 3.91 or 4.30 gears for drag racing. Out of 13'000 mustangs in 1969 all were Mach 1's except a thousand.
"Just the Facts, Sir"
1969 Mach 1 production, 72,459.
Q Code Engine production, 105 Hardtops, 2,765 Fastbacks, 50 Convertibles.
R Code Engine production, 138 Hardtops, 11,287 Fastbacks, 317 Convertibles.
Most of those Fastbacks were most likely Mach 1's. It is all good there jhanley, just my OCD catches stuff easily, and I missed the Mach 1 part of the story. Have been to many a Mustang show from Vancouver, Victoria, Seattle, Spokane, and points in between. The non Mach 1 or non GT, that are equipped with a 428 really stand out in those shows.
