Yes they did, in the 6000 to 7000rpm range, making 600 or more HP,
they do have a tendancy to crack the block in the #3 crank journal up
to the #3 cam journal. This was corrected late in the production run
for the 428CJ engines...
However, we're talking about a low rpm truck application, so there
are no problems with the block unless a complete idiot is behind the
wheel...
