Whats everone working on?

I am working on finding a better rear end for my 68 cuda fb. I have a fairly strong 318 in it, and the itty-bitty 7 1/4 rear end is gonna go south on me soon. I also am looking for a good deal on chrome shafts for my new roller rockers, and once I find 'em I will install a new hughes cam, springs, lifters, roller rockers, new water pump (the original reason for this whole proceedure!!!)old school M/T valve covers, and my Offy 360 high rise, till my new/used Holley street dominator gets here. I will also switch to a holley from a carter at that time. As to the 7 1/4, I found one on craigslist with open diff and 3.23's, and I was gonna buy it and put an auburn or some such in it with new axles, but no one makes an lsd for the 7 1/4. I figured if I had done it that way it would be strong enough for normal use, and I'd also have the 5 on 4 1/2 all around then, but I am back to the drawing board and will have to incur the expense of a new drive shaft and etc once I find a suitable unit. 3.23's to 3.55's are my target ratio, with a final drive of 6.1-6.33. I have an A999 wide ratio transmission and I think a final drive of 6 to 6.5 will be fairly quick while still giving me some semblance of economy. I hope!! I'm sorry for the long post, I think too much!! Oh, and if anyone has smallblock headers for cheap I'll buy em.
