Mine weren't that bad left them cooking for probably about 8hours but the worse they are the longer it takes,also depends on charger output.

What amp setting did you use? I have a Shumacher charger, 10/40/200A or should I get a smaller unit?

My charger is 20/100 so I must have set it on the 20.  So Id put yours on the 40 and just keep an eye on them. There is lots more info on the net if you search electrolytic cleaning diy. You can always cook them for a few hours take them ou have a look and put them back in if you need to. It is quite a slow process, but as long as you haven't already fitted brass guides (process doesn't like non ferrous) you should be fine.
Just found this goes a bit deeper into it than I did.

I have a deal made for an 850DP. A good buddy/fellow racer rebuilds/modifies Holleys to sell and he built this carb recently, the carb was too much for the buyers engine so I'm going to buy it for $250. Mike said it was in like new condition when he got it, original factory jetting and etc. The choke horn has been milled off and it has notched floats, jet extensions and etc already. If it doesn't show a decent gain Mike said he will buy it from me - hard to lose in that deal..LOL...I'm sure it will show a gain and having Mike help me tune it is a bonus, he tunes a lot of Holleys around here - my current jetting was his suggestion and it was dead on when we dyno'd it....Lucky guess....LOL...I should have it in my hands next week.

Will do, I hope your right! I sold my d TCI converter and my old front skinnies last night - perfect way to pay for this carb swap. If the 850 works I should be able to get $400 my old carb with the notched floats and etc being in it.

Your a hard man on my wallet....LOL....Lets wait and see how this goes, next winter I'd like to do some head work, maybe a victor intake will be in the cards then too. And I still want to rebuild my tranny with some roller bearings and etc. It has 15 seasons of race use since it was rebuilt by the guy I got it from. Still works great though, just a stock VB with a shift kit, TCI servo and aluminum pan. Gotta love those old C6's.

Just rebuilt my own C6 reasonably straight forward got a dvd from http://www.badshoeproductions.com/ which was really good. Have never rebuilt one before. Got the 500hp rebuild kit from Jay at http://www.broaderperformance.com/ really good to deal with and the rest of the rollerizing I got off of here and the 460forum. A guy from Australia called Gregaust on here sent me a load of photos I can pass them on if you like. I'm sure he wouldn't mind.

That would be nice. I bought a couple books and my buddy has a tranny shop so I should be good to go when it comes time. I have four 2wd BBF C6 trannys here counting the one in the car. Two car and two truck versions. Car version in the mustang now.
