33's and a speedo

I never finished school, and don't know number well lol. But how far off would you suspect the speedo is off on a 87' 302 running 33 in rubber..?

Should not be off much - if at all.
Its when you start playing with gearing when it goes crazy.

I have 33's on my 95 and I believe the speedo is off about 5 to 7 miles an hour, depending on how fast I am going
