whats the highest rear end you can run for a street car i have a 390 gt do you think i should go from a 3:00 to a 3:25 and wiil there be much of a difference or what about a 3:50 or is that to high for street use
Id say 3.50 is max for a street car that see's highway use as well. I have 3.25 in my Fairlane 390, and its great for my type of driving (everywhere). If you see little or no highway, go with a 3.73 or so, that'll wake it up.
