speedo help for th400
I have a 1972 monte carlo with factory th400. I just switched from a 2:73 to a 3:42 gear in the rearend and I am showing a faster than actual speed on the speedo. Does anyone know how to figure out what speedo gear to use in the trans or where to get one? thanks for any help you may give.
That's going to be nice, like the color. .
