A 421 HO was fitted at the factory or Royal Pontiac (depends on who you ask).

Well if you ask Jim Wangers, as I had the good fortune to be able to do most recently, the 421 HO swap was, in fact, a factory effort.

Oh, and it spun the #6 rod bearing during testing. Was flat-towed back to Royal by the blue GTO pilot car (which was 348 powered). The blue pilot car was crushed (also a factory effort) shortly upon return. The red car (er, this one), fresh "Bobcatted" 421 HO in place, was given to Jim as his demo. It was never modified beyond this while with Jim.
