So here I am - at another crossroads during my muscle car build up. I am in the process of building my choice street machine, and the funds are dwindling. I am sure I am the only one that this has occured to right?

Anyways, long story short. I am looking for some ford 9" rearend advice, as I wait until next year to fund doing this right. I currently have a noisy 3rd member (3.70 gears/28 spline) sitting behind a brand new 500+ horse 402 BBC and a new TH400 trans. It makes a nice noticable hum (not to mention vibration) at about 50 MPH. It seems to only happen when there is positive throttle engagement. Once I let off, it goes away.

I would like to go with the Strange 3rd member/rearend setup, 33-35 spline axels, etc... but this will be next year. Any recommendations on rebuilding/fixing the current config, or would it be approx the same cost as just putting the money into my new config. I think I can make it thru the summer, but its annoying as hell, not to mention I am having fears of breaking the rear-end thus ending my radical summer fun.
