GM's move to CalPaks

[Walter Sherwin]

Someone must have really goofed in the catalogue department
then.............

The 16147060 is beyond a doubt a PCM P6, available in the 91-93 454SS C1500
trucks (7.4 & 4L80E) as well as other 91-93 trucks equipped with the 4L80E
electronic 4-speed auto trans.  MT1 is the RPO for the 4L80E trans.  R2 is
also another internal GM engineering reference to the 4L80E trans.  Uses a
MEMCAL with a SNEF & RFD resistor network & 27C256 Eprom inside.  Was only
teamed up with 2bbl TBI and 4L80E.  Pretty good little box.  There are some
bin's in the ftp incoming directory.
