Jack, I've browsed the usual places and likewise do not see any specifications for compression pressures; the highest compression reading for a cold engine that I got from my 374 engine (when it had about 80,000 miles) was about 155 psi.

Per maintenance records, on 09/13/2014, the CCP on the 352 in the 56J, with 94,000 miles on last rebuild, was: #1: 155; #3: 150; #5: 175; #7: 175; #2: 165; #4: 170; #6: 160; #8: 150.
Not sure what the OEM spec was but agree the spec in the S-P manual is pure hog-wash.
