Here's a tidbit I picked up that I thought you might be interested in... .
"..... Today I was fine tuning my pump on the 92. Since the 90 model feed truck was right by it. I decided to pull the diapraghm off of both. After I got the 4 cap diapraghm off, I noticed that the 90 models eccentric cone was tapered alot more(allowing farther pin travel) than my 92's. The 90 models eccentric also showed a different stamped part number than the 92. The 90 models was a 75 while the 92's was a 70H. This can be found on the bottom of the eccentric cone. So, I switched the 90 models 75 into the 92 and took it for a ride. You could definately tell a difference. In fact, instead of boost stopping at the 32-33 mark, she went right on up to the 35 mark. Quickness of the truck off of acceleration was definately noticed between the two. So, if you havent already, check your eccentric number, and, if you can find a donor on a non intercooled to compare. The 90 model is a 3/4 4wd Automatic with a CPL of 0807 and the 92 is CPL # 1351. ... . "

Maybe some measurements could be taken? This is getting really interesting now (see "VE Pump" topic).
