Greg, not that I'm a FFFord guy but the original 50 681/2 CJs had aluminium intakes. The passenger cars didn't but, NHRA isn't going to start checking VIN#s to see which are which so they let all of the 68s have them. The 69s shouldn't have gotten the aluminium intakes.

Billy, those cars if you remember ran SS at the 1968 winter nationals. The reason that manifold was never in the book for stock is that it was never approved for stock.

Greg, my point being that they are now legal for Stock just like a T-Bolt or a 68 Hemi Cuda and the aluminium intake came "stock" on them. It did NOT come on any 69s.

Ford's 428 Cobra Jet engine made its "en masse" drag racing debut at the eighth annual National Hot Rod Association (NHRA) Winternationals held from February 2 - 4, 1968, at the Los Angeles County Fairgrounds in Pomona, California. Ford Motor Company sponsored five drivers (Gas Ronda, Jerry Harvey, Hubert Platt, Don Nicholson, and Al Joniec) to race six 428 CJ-equipped Mustangs. The Mustangs raced in the C Stock Automatic (C/SA, 9.00 - 9.49 lbs. per advertised horsepower), Super Stock E, and Super Stock E Automatic (SS/E manual transmission, SS/EA automatic transmission, 8.70 - 9.47 lbs per advertised horsepower) classes. The engine lived up to expectations as four of the cars made it to their respective class finals. Al Joniec won both his class (defeating Hubert Platt in an all-CJ final) and the overall Super Stock Eliminator (defeating Dave Wren) title.

Information from the 428 CJ Registry.

Wrong Billy. The original 50 did not ALL have aluminum intakes. Only the cars that ran SS were allowed the aluminum intake along with flattop pistons and the .600 lift cam. If they had all come with aluminum intakes, they would have all been allowed to run that way since 1968.

Like I said, I'm not a FFFord guy. The fact still remains, NHRA isn't going to start checking VINs.
Jason, maybe you should bring this website up to the powers that be at NHRA!
