I am more likely to throw 305s/275s up front now, as I think the added weight and rubber would help... first gear is hard to use now in sub 50 degree weather. Id say of anything I have done, this is the most obvious enhancement.
but this gear whine has me a bit bummed... I need to go back to the shop and see what the deal is with the whine, and how it could be fixed.. From what I understand I should not have noise like I do.. I have a short video going 75-80 on the highway... you can clearly hear it in the video, if anyone cares to hear it, PM me.

Whine is not good. I bet you have spun your wheels and created axle hop. Can't miss it ....... sounds like a set pounding drums coming from the rear end and you swear it's going to fall apart. Either way, it sounds like the pinion gear is out of adjustment (bushing may have pounded out) or you have damaged a side carrier bearing from the axle hop.
Unfortunately, the only way to be be sure is to pull the rear diff and perform a inspection of the bearings and clearances. Chances are a rebuild will be necessary.
I had a severe case of axle hop on the drag strip and damaged the rear diff, as it now has gear whine, as you have described. I'm rebuilding it this spring and looking into rear diff braces and solid mount kit.
