Correct RPM

I'm trying to evaluate my 110,000 mile 92RS. Does anyone have any idea what the design parameters were for a stock 92 RS w/ TBI , 700R4 and 2.73? I assume my tach is at least slightly off but soon I'll be datalogging (if I can ever get this cable right). I'm hoping I can get the car a little more efficient. It's become my DD.

Re: Correct RPM

Various MPH. I know this is vague but this site is loaded with info from long ago and the search is now a shaky proposition.

Re: Correct RPM

A quich check with the 700R4 would be 40MPH @1000 rpms in OD. This worked with my 305 and also with my 350.
