I bought the Banks system directly from Banks themselves. I got the whole caboodle, it was around 1800 bucks. They recommended a fitter near here (ABC Muffler in Benetia) and shipped the system directly to them.
ABC charged me 600 bucks to fit it. They did a good job, although didnt know about the lean mixture issue, or the advance the timing 2 degs issue. The coach went much better as soon as the new system was on...however...
...I called Banks about the now terrible gas mileage (4mpg) and they told me about these 2 things. I then had a complete run around to find anyone who knew about 454 carbs. I finally found an eccentric "Dead Head" hippy mechanic somewhere in Marin who specializes in vintage carb rebuilds (I mean 30s and 40s vintage...) and he was able to find the new needles and figure out what to do to make the mixture richer. This is complete try it and see stuff. There are about 20 different needles made for the 454 carbs...he charged me a very reasonable 75 bucks, although I fixed up his computer for him at the same time, heh fair trade etc...
I hope I pass smog next year...
Anyway he couldnt advance the timing so I went to Oakland Truck Center who did this as part of another job they were doing. This was likely to have cost 50 bucks maybe...
Ans to Peter's question I have an MSD ignition system on there.
This makes a big differnce too. I also found replacing the distributer and all spark cables and plugs helped alot. I used stock GM parts for this.
It has been a labor of love to get this engine running as well as it now does. Touch wood it is now running absolutely wonderfully.
I cannot recommend the Banks system for this machine highly enough.
I can cruise at 85 towing a Suzuki Samurai if I want too (not realy recommended...) but I could, and the acceleration is not too bad considering it is an 11 ton or so piece of machinary...
Other things that have made a HUGE difference to the power - change the gas filters often. Airstream say every 15,000 I would say every 5 to 8,000 if you go to Mexico ever <grin> I might get to checking how much crud is in the bottom of my fuel tank too at some point soon.
