Here’s the rest of that 1971 factory Dyno session info as provided by Pete McCarthy in the 1996 Sept/ Oct issue of Pontiac Enthusiast magazine.
Test 1 and 2 would have been with the RA4 Cam without 1.65 rockers and with open exh.
The other 4 test with the M-7 Cam as Pete says in the article would have likely been the RA4 Cam but ground with a 100/110 lobe separation.
You 455 owners out there running tight lobe separation cams thru exh manifolds are missing a out on a lot as this test shows.
