I'm capable enough under the hood (engine-side), but have never changed a differential (back-end) on anything I've owned. I've seen some references (specifically for the 289-powered Hawk) to swapping the 3:31 differential to a 3.07. I see a number of posts (including June 2018 thread on "Changing '65 Borg-Warner to GM powerglide") but I think I need a quick explanation - and if possible, with specifics of putting the stock 289's power to the road. Plenty of info out there on differentials -and I know the basics, but would like to know what's common for my 1960 Hawk. My engine is stock, but for an upgrade in carburettor (2bbl current, 4bbl planned, everything in-hand except the time). The car has overdrive, and it works well.
I'm just trying to figure out if I'd benefit from anything here. I also have a '62 GT without overdrive - and I also interested in finding ways to smooth out/lower-revs at highway speed.
Thanks for any insights.
