ASTOCK here is an excerpt from the Pontiac GTO Restoration Guide. Page 381. " Finally, the Ram Air IV Super Duty: Research indicates that approximately seventy of these engines may have been released for public consumption in 1970. The Ram Air IV Super Duty consisted of a Ram Air V bottom end and Ram Air IV heads, intake manifold, and carburetion. No Ram Air V engines were released from the factory for public consumption, although it was possible to order all the necessary Ram Air V components over the counter. Occassionally a Ram AIr V will turn up, but it was not built on the assembly line for sale in a 1970 GTO. Evidence also indicates the installation of a few RA IV SD engines in 1970 Trans Ams. "
Read my previous posts if any dealer would have access to a RA V engine it would be Knafel or Royal. It was dealer installed and many people will back that up.
The Ram Air V was a counter motor. Unless someone has a specified code on a legitimate build sheet or PHS that states RA V then I will stand by my statments.
