What engine do you have? I had two different 1970 Chevrolet Tilt Cabs and one had the GMC 478 V6 and the other had the 427 V8...both were 5+2 and both had a max speed of about 53 mph.
Do you still have the John Bean booster reel hose nozzle's? (click on IMG link if the picture of the nozzle doesn't appear)
Does your truck have two pumps (High Pressure Fog and the mid-shaft Volume/Pressure Main Pump)?
Are there two axes on the back panel?
Here's a picture of my 1957 Chevrolet/John Bean.
