My two cents might help or at least get some gray matter stirring. Back in '88 I packed up a '69 camaro with the 2 1/2 turn variable ratio box,after buying alot of manuals and investigating I found out these were supposed to be popular in 6 cyl cars and this one was. I bought it with a 4 bolt 350 so I didn't mind the wrong codes,VIN,ect. Around '90 or so Popular Hot Rodding Mag had an article about modding your P/S pump for more effort and feel (lower pressure), I tried it and loved it. I think the reverse should work on the old pumps (I don't have the article any more) but I have no exp on the new pumps or boxes. Hope this helps someone out there.
