Car is a 455 HO with the same Ram Air system that was available on the 400 RAIII.

The 70 455HO is a unique creature as the compression was around 10-1/2 to 1. In 1971 the 455 (and everything else in Pontiac land) dropped to around 8-1/2 to 1. So It is a unique engine given it's one-year availability. As you may know, with Pontiacs, the compression ratio is created by the cylinder heads not the pistons. Most of them use the same type of flat top piston with valve reliefs. No domes here. So this engine will have a rather rare set of heads on it with small volume chambers.

All the 70 GTO's with the 455 engine option had the same 'ho' engines. The ram air is just the scoops/hood/cable. No difference in the engine. It did not even have ram air headers. Where as the 71 455 ho engine had many upgrades over the 455 that was in 1970.

For that $57, you got the only 12 bolt that came in a GTO, and 55 more cubes. One of the better deals that not many knew about.

I don't see where he is saying the car was built to RAIII or IV spec? He just says it is a '70 455HO, which it is. And this engine was rated at 370 HP when used in other Pontiac cars for '70.

It has the ram air hood and cable pull on the dash. Could you order a 455 with the ram air hood. So it is not a ram air ii or iv, but still a cool car if original. I would like to see the PHS documents.

The Broadcast sheet from inside the car was in the ad but not the actual PHS sheet from Pontiac Historical, other than a remade window sticker (probably by PHS) which isn't really worth anything for documentation purposes.
The PHS issued version of the broadcast would be the ultimate corroboration of the broadcast sheet in the ad. He should add that to the listing. Cool car other than the yellow and tan color combination. A one-year-only 455HO, four-speed with A/C and Ram Air hood option. Very worthy of restoration.

Yes agreed, if that car was Starlight Black with red guts or Polar White or Atoll Blue with blue interior it'd be sold now

Heck, if that was black and red I would have bought it. I still have flashbacks to June 1970 at summer camp when the cool counselor showed up in his brand-new 70 GTO, black with bright red interior and the optional rear wing. I’d love to have that car. Made quite the impression on the 7 year old me. Even more than the tie-dye wearing, lady counselors in their hip hugger, hot pants. :-)
