I'm in search of solid places to find accurate, detailed information (parts interchangeability, rebuilding, performance tips, etc.) on the Pontiac 389. A search of this forum didn't gain me many hits. Specifically, I have the opportunity to buy a complete 1959 389. I've been able to piece together a decent understanding from multiple websites (reverse-flow cooling, bellhousing options, etc.), but I haven't found a website or forum dedicated to the 389 or at least with a large population of members discussing the 389. Any resources are appreciated.
