I will be rebuliding the c5 soon,but i need to know some key questions before i buy anything ( i don't want to be buying stuff i don't need) Will i need a 4pack drum? This tranny came from a v6 i have herd they only have 3pack drums or something like that not sure. also the C5 VB dose it need to go in order for me to run a trans-go shift kit? I want this trans to be able to handle atleast 300-350 hp street motor. I plan on keeping the B servo becuse it works well now.
also where can i find 157th bells they seem to be hard to source down

Have to see what drum is in there. The ones i've seen even though less clutches have thicker plates and wave plates instead.
Valvebody really need a c4 one
B servo is very small apply,not saying it wont work but i only use the B in stocko setups.

Well i would like to know before any tear down starts. Its a 83 model c5 came form behind a 130hp 3.8 v6
I know i sound very cheap but, I really don't want to be buying a ton of hard parts. I might aswell buy a REG C4 which i could prob do cheaper. So buy stock v8 spec drum,C4 VB anything else iam going to need ?? ohh yea H servo

OK after searching around i have found a v8spec 4pack drum at bulkparts. Iam just guessing the c5 that i have will have a 3pack one (just a guessing) Next thing is valve body to be honest the stock C5 one i have bangs good and loves manual shifting. As much as i would like to go full manual i kinda like the ideal of having the option shift (if u want to) thinking trans-go shiftkit with reg c4 VB. What you experts think?

Here's a suggestion since you seem so reluctant to open the C5 and would rather guess at the internals - go to the yards and look for a 70 up C4 in the tranny pile. You might give $50~75 for the core. Fresh those parts and VB and stick it all in your C5 case.

Not that iam reluctant, just that the tranny is still in the car and running. Maybe i should just wait and pull the tranny tear it down then order stuff from there. My luck with being lucky is never good though.

That's the best thing to do. Don't order parts until you know what you've got.

306merc,
The C5 has only three drums listed in my parts book. They list a 4 clutch and a 5 clutch forward and a single drum for the direct clutch which is a 4 clutch drum. The C5 uses thick and thin pressure plates to fit less and more clutches. Your drums will be fine. For the HP of your engine you need to get a couple of the thin pressure plates and a selection of the top lock rings that come in different thicknesses. You will need the 1970 or later valve body from a C4 no matter what. You will need a converter, 157 tooth ring gear and flex plate and the small V8 bell housing. I would wait until I had it torn down to figure out what I needed. If you have alternate transportation that is always the best way to go. If not be sure that your parts source will take back what you don't need. Are you getting a master overhaul kit that has the clutches, steels and bands? or just a gasket kit and then ordering the other parts as needed?

You can't go wrong with a Broader C4. They make good transmission and I can easily recommend them.
When you get the Broader C4 in place then you can take your time and build the C5 as a replacement. Get all the parts prepared and ready to go in but don't assemble it until just before you need it. Sitting on the shelf for even five years will dry out all the friction materials and they won't hold like they should. Also they can collect moisture and rust internally just sitting around empty. You can practice putting it together and back apart until you are more comfortable doing it.
With the Broader tranny you may wait a long time before you need a spare.
