Would like to know about 396 vs. 402 big block
motors........why the jump to 402 cu. In. from 396 cu.in. and about when the
change took place. I also have heard / read to tell the difference between the
motors the 396 has a two letter code ( ie JC ) and the 402 has a three letter
code ( ie CDE ) .
Thanks,
