I've bought two of the HEI's for inline 6 cylinders off ebay. They worked wonderfully. One is still installed in my wikivan that I drive everyday. Its been there for a few years so far with no problems. Excellent upgrade from the crappy points stuff.
Skip white is a good seller and stands behind his stuff. I've bought a bunch of stuff from him, so I can personally attest he is a good guy to deal with. If you got a bad HEI, send it back and he'll replace it no problems.
The only issue with the large cap HEI is that they take up alot of room in the doghouse. It fits, but it is tight to the wall in a 1st gen doghouse. You will also need different plug wires, so budget for new wires, and you will need to do a little re-wiring for the HEI to eliminate the points style resistor wire in the stock van's wiring.
Assuming you could even find a chevy inline six at a junkyard, chances are the used HEI would probably cost you almost as much as buying a new one off ebay.
