There was timing information in manuals for S/370 processors, e.g., 
http://bitsavers.org/pdf/ibm/370/funcChar/GA22-6935-0_370-165_funcChar_Jun70.pdf.

Unfortunately, the formulae for each new model were more complicated.

Not since pipeline processors. The last time I saw a manual with timings was 
for a S360.
