I have a 49 Chevrolet 3800 with the 17" 8 lug wheels. I want to convert the front brakes to disc, but I'm hoping one or more of you have already done this and know where to start. Does any one have any idea as to what to do? I'm keeping the stock suspension. I just want to add disc brakes.

Jason,I'm more clued up the smaller trucks but I think this link might help.
There's a fair bit of reading but hopefully it might help you.
Good luck!

Yep, that link is what I know so far about adapting disc to a 1 ton.

Realize that there is more than one way to skin a cat, so if you come up with something else let us know!

That method sounds great if i had a heavy dually, but my truck is a fairly light duty single rear wheel ruck. I'm going to start junk yard shopping for a disc brake rotor that I can bolt in place and then maybe make s steel plate to hold the caliper. I would have to find a way to change the bearings out in the hubs to modern type, but I think that would work. Also, those parts from the P30 and HD3500 are a lot of weight to ad to the front of a light duty truck. I know that I had a 1941 Chevy 2 ton truck that I was able to un-rivet the original brake drums from the hub and simply bolted modern Chevy 4 wheel drive 6 bolt discs in place and made a simple bracket to hold the caliper. It worked great.

I have the part numbers somewhere if I dig for them...
Here's the writeup on that process
https://www.stovebolt.com/ubbthreads/ubbthreads.php?ubb=showflat&Number=605450#Post605450

There are now aftermarket tapered roller bearings available through some of the usual restoration parts suppliers for 1 tons (and nowhere else that I can find).

That is pretty much what I'm thinking of. The only deal breaker that I can see is the wheel clearance. My truck has the stock 17" wheels, so that probably won't work. There has to be a smaller rotor that would give me wheel clearance.
