That is a fact on the other GM cars I own or have owned as well. GTO is the same issue and Camaro the same deal. Must have been a corporate decision. Vikki, do ALL 400 cars from ALL plants show the '3F' designation in 1967 that you know of?
1969 Firebird 350 Coupe, Rust free Texas body, formerly brown, now a TA clone with quality spoiler, latching hood and TA wheel; 1969 GTO Convertible Expresso Brown/Parchment(currently painted red). Both numbers matching. My first love was a Cameo White 67 326 Coupe, bought back in 1983, at the age of 17, for $1,200. Been hooked since on PONTIAC! Working on a 67 400 ragtop for customization-Gulf Turquoise/Parchment/400/4 spd! My winter project!
