Hi nice collection,

How does the chev + th400 + 4.6 ratio diff go? My 350 stroker has the same box but a 2.78 diff and I want to change the ratio to a 3.08 or a 3.36 but I don't know how the car will cruise, I don't want it pinging of its head at 150km/ph. I still want to be able to drive it on long trips occasionally.

Cheers
