Another theory as to why the W-30 may sell for more in todays market is the cost of restoration. I'm not certain of this, however it may cost more to restore a '70 W-30 442 than a '70 455 GTO. There are probably fewer repo parts out there for 442s than GTOs. When was the last time you went to a swap meet and ran across an Olds W-30 aluminum intake, "F" code heads, "W/Z" code exhaust manifolds, OAI air cleaner, W-25 air induction fiberglass hood, "OW" code Turbo 400 transmission, Hurst dual gate shifter, rally pac guage cluster and all the other goodies that make up a W-30? Very rarely do I attend a swap meet and find an Olds vendor, but I can find at least one vendor selling Pontiac parts.
