Ted,



Just FYI, the Ford parts book for Panteras shows no less than FOUR different

pistons for various Clevelands ('71 4V and CJ used D0AZ 6108-A, then '71 Boss

used D1ZZ, '72 Boss used D2ZZ and '73 4V used D3ZZ) not including overbore

pistons!



I think the Boss pistons were pop-ups, and were probably not used in

Panteras.  Just a guess.



Also, three different cylinder heads for '71/72 are listed; 4V, CJ,  and

Boss.  We know Panteras never came with Boss 351's, thus one can assume they

did come initially with 4V (D1AZ 6049-B) and later CJ (D1ZZ 6049-C.) which I

presume are different somehow (larger combustion chamber in the CJ head for

lowered compression?)  Then for 1973 they list only one head, the D3ZZ6049-A,

which I presume is the open-chamber head, actually introduced in the middle

of '72.  



There, does that muddy the water even further? :>)
