904 transmission shift issues...
Do you guys recommend a throttle linkage adapter that will make adjusting easier?
Yes absolutely needed; Holley part # 20-7 http://www.summitracing.com/parts/HLY-20-7/
I have an older Holley 390, 904 automatic transmission, Holley part # 20-7, and Bouchillon kick down cable kit, this combination is fully adjustable. The only thing you need to be sure of is that the accelerator pedal when floored will fully open the throttle plates in carburetor. I had to place a 3/16th inch between the accelerator bracket and floor. If throttle plates won’t open fully the secondaries will not open. There are other cables the work as well.

Get a factory service manual for the year of your car. They are available in print, and on disk; personally I prefer print copy as one can mark it up with notes, and drag it under the car while working.
As for rigging up non stock carburetors, manifolds etc. you’re kind of on your own relying on us here, or that other /six site dot org.
I install an o2 sensor to help tune the old holly, it helped. You may want to take a look at this site for a few Holley tuning tips http://www.bob2000.com/carb.htm , and get this book covering Holley 4160 (390) carbs; http://www.mre-books.com/fuel/hp473.html
