70 Chevelle 4 wheels disc conversion

[Saleen04]

I've been away from hot rods for a couple of year and just picked up a 70 Chevelle project car. I'm looking to do a 4 wheel disc conversion as it currently has drums all the way around. Since I have a several major projects on the car I'm looking for the best without breaking the bank.
The is being built as a street car and will have between 400-500 HP.

I would be open to finding used breaks as well such as a Z06 or C5 setup just not sure what will work.

Can you make suggestions which are good kits to go with?

Thanks

I've see this on ground up:
