Reply to "Pantera Engine Blocks"

Officially Ford states that all 351c Cobra Jets were D2AE-CA 4 bolt blocks.

There are lots of individuals claiming that they have original 2 bolt Cobra Jets. There may be confusion here of some thinking that all 4v 351c's are CJ's?

That is not so, but you can't talk to them. They start yelling at you. If you show them Ford documentation, they tear it up and set it on fire.



The heads that you have should be the closed chamber 4v heads that were used on the 1970 351c 4v's. Boss heads would have the same casting numbers but would be machined for screw in rocker arms studs, push rod guide plates and use adjustable rocker arms and a solid lifter cam shaft.

The drip tabs mounted inside of the valve covers were intended for  use with the solid lifter valve train. Not hydraulic lifter cams and valve trains.

I bought a set of Boss 351 "Service heads" about 1976, and from memory, so don't shoot me if I get the numbers wrong please, the head casting ID was D1AE. The box they cam in were marked I think, D1ZZ-A or AA?

When I went to sell them the guy who bought them started yelling rape or something like that, demanded his money back and said these were fraudulent as Boss 351 heads were marked D1ZX in the engineering casting number...and said I did a lousy job on machining the pedestals to boot. So be warned, some people are very touchy about this stuff even though they are incorrect about the details? Just sayin'.

Never having had a production line Boss 351, I couldn't refer to it for any kind of confirmation so I just refunded his money so he would stop waiving the shotgun around and scaring the neighbors. So far to this date, I have never seen a set of heads with the D1ZX on them, but admittedly, I have lived a sheltered life. I still haven't been arrested even once. So what does that say about my worldliness?

Odd because friends constantly ask me that?



It's all good but as the Cleveland is originally applied to the Pantera is a little different from other Ford applications, the Pantera may not be the examples that you want to model after? Many aftermarket modifications are applied to Panteras because they fit the Pantera better and are not necessarily what you would want to do on a Mustang or Torino, etc.



Here is a good source of some technical information you may be asking for. It is not complete as far as the 351c goes but may help.

The CJ is the first 4 bolt block BESIDES the 71 Boss and the 72 HO. I believe the Boss was a D0AZ 4 bolt block only available in the production line Boss 351 and the HO was a D2AE-CA 4 bolt block?
