Yep, 281 and a 306 school bus engine were also 30 inch flatheads with 12 ports. The 281 was normally a "T136" designation, 1946-47, in WJ 55-59 vehicles. 331 was a "T135" in 46-47 WK 65-69 and WR 65-69 vehicles. Info on the 281 and 331 comes from "T Flathead Six Engines" on the net. The info about the 306 comes from a guy who got at me on ebay who should be an administrator on a Dodge Flathead site. He knows his stuff.
