Yet, Ford did not use any of the second generation big blocks in pony cars like the Mustang at first. With more than 400 lb-ft available from 2,600 to 4,700 rpm, the Mach 1's tail is sure to be obscured in clouds of tire smoke. Not too common, maybe a total production of 15,000.

The valves are bigger but the real improvement is the exhaust port which is both wider internally and straighter plus higher exit point in the casting. This is an internally ballance assy . Though I've seen references to engineering numbers on flexplates, I've never actually seen any kind of stamped or cast number on a flexplate. Ford quickly caught the vision, and before the drag-ready Mustang returned to Tasca Ford, Ford Engineers removed it from the vehicle so they could reverse engineer it for mass production. In order to keep the car eligible for the stock NHRA category, Ford capped power at 430 horsepower. So there was an overlapping period of perhaps a year from say June 1967 until June 1968 when both types were being made and used, apparently for both CJ and non - CJ applications. You can use the 428 crank in the 390 block and will end up with 410 cubic inches (Ford actually had a 410 for a couple years). The 428 SCJ was first introduced during the 1969 model year. Craft notes that one significant change for 1970 was the inclusion of a rear sway bar for Cobra Jet Mustangs.

The 396 featured advanced-design, canted-valve cylinder heads that flowed like crazy and earned the name "porcupine" because of their splayed-valve arrangement. As a result, the 428 was less rev-happy but it gained a low-end torque punch that was absent in the 427. If you don't put the 428 in it you should get a 460 instead of the 429 for even more power.

To verify an original car, you can simply look at the vehicle identification number (VIN) on the dashboard. The value is markedly different (about double). As it turned out, the 427 heads massively improved both low-end torque and top-end power on 428. Ford was not caught in flagrante delecto, however.

The name is perhaps one of Ford's most enduring performance legacies. The 396 was known in Bow Tie circles as the Mark IV and was further known as the "mystery motor" because it was developed in secret for the '64 Daytona 500. You true FE gurus can add/correct info to the above. The CJ 428 engine was the top-of-the-line performance option that replaced the former performance heavy-weight 427 CID V-8 in April 1968.
