I think you can supercharge your SC minus the CIS upgrading for no more than say $1000 - 2000.

Why I would go the SC route for simplicity and cheapness:

1. Cheapest to build hands down due to far less components than a TC.
2. SC's provide low-end grunt/torque most TC's cannot replicate without serious upper-RPM hp limitations.
3. You don't have to use an intercooler until high boost levels (say 10-12psi+).
4. Opposite of turbos, the bigger the SC is (of course a point of diminishing returns), the more power it makes due to lower exiting air temperatures on non-IC'd setups.
5. Less headaches due to less sytems like WG's, IC's, etc., and less plumbing.
6. More room due to less plumbing.
7. Keep factory heat without replacing expensive headers.

Anyways, here's what I did on a '69 Camaro that would be pretty much the same as your SC - some of it sounds really shadetree but it worked for my car:

1. Build brackets out of 3/8" to 1/2" aluminum for a centrifugal, 1/4" steel for a screwcharger........very little $$$
2. Buy used pulleys for the SC and crank from Ebay or others.....very little $$$
3. Make or buy the oil pressure feed line (for centrifugal).....very little $$$
4. Pop a whole in one of the chain housings for oil return (for centrifugal).....very little $$$
5. Go NAPA's warehouse and look for assorted heavy equipment radiator hoses for the discharge side of the SC to the CIS.....very little $$$
6. Go to Home Depot for PVC plumbing for the inlet side of the SC. You can make just about any curve you want......very little $$$
7. Acquire a BOV - minimum would probably be like 2"......these are a little $$$ but not bad
8. Belts are very little $$$
9. Assorted fittings for the oil lines.....very little $$$

There you have.

BTW, I have a perfect SC for sale for you: Vortech S-trim (680hp capable)

Regarding upgrading the CIS to handle boost, I have no idea but I am confident you can find out from these guys here.
