You only live once! I am glad to see the '64 is not garage art. But, you are not running a fuel dragster or funny car with a blower and nitro methane. The parts will be just fine with some "meats" on the back. Just not too sticky of a compound. A pair of Mickey Thompson Sportsman Pro's should be just right. Nice picture of the rear of the '64 at the Dream Cruise with some slicks on it. We should have had the two cars parked next to each other. At least they shared the same location. Eric

Early 1968 GTO Royal test session
Here is another 1968 GTO Royal Bobcat test. I want you to note all of the people involved in this test watching from the fence. Thes are the guys from Royal Pontiac.
Sessions like these are private track rentals. Closed to the public. Royal Brought out approximately one car person. Jim Wangers would orginize a large test session like this with several cars and different magazine banners being drapped on the cars to represent the magazines the cars would appear in. In this case you had Firebirds and GTO's. Dave and Sid Warren seen working on the cars. John Kosmala behind the wheel of the GTO with a Firebird ready to go with driver. Between the GTO and the Firebird you see Milt and Dave Warren along with some I can't I.D. The is an example of how it is done. Several cars at one times. Not a test here a test there. This was done before the ram air II heads came out for 1968 GTO and Firebird articles I have already posted. Then after the RA II's came out a new barrage of magazine tests. Look at see if it was at Motor City Dragway. Then study the background for other cars that are being tested. Most of the time every one tried to stay out of camera view. Including equipment, extra tires and other cars to be tested. Much easier to bombard the magazines early. The magazines would spread these early tests out through the year. As the model year goes on and the cars get faster. More Royal tests would be published. Got to keep the HOT Pontiac's in your face all through the year. Enjoy the going back and forth to study the articles and people, cars and equipment in the backgrounds. Mostly at Motor City Dragway, Lapeer Dragway and Ubly Dragway.

The big difference is Ram Air IV's had bigger intake ports than the Ram Air II. The Ram Air II shared intake port size with the typical 1965 and up D-port head and was the first round port exhaust head. The 1971-72 455 HO and the 1973-74 455 SD had the bigger intake ports along with round exhaust ports too. The 455 SD intake ports were slightly bigger then the Ram Air IV intake ports. The 455 SD intake ports broke into the push rod holes and valve cover bolt holes. Tubes were inserted into the pushrod holes to seal the port and valve covers bolts must be in place and installed with thread sealer to prevent vacuum leaks.

1968 Royal Pontiac's winter testing was done in Florida around February so the articles would hit the magazines in spring.
Here is the early testing of the Royal Pontiac's Royal Bobcat 1968 Ram Air engine vs the 1968 1/2 Ram Air II engine. Along with the information of the no extra cost of the new Ram Air II over the Ram Air I and the release date. Look closely at the two GTO's. The Bobcat paint is visiable on the nose of one of the GTO's. Both cars have the pin stripe and Bobcat emblems on the front fenders and doors. Enjoy.

This might be pointless but I think the RAII should have had the 744 cam and the RAIII with round ports 041 with 1.5s for 69 and RA IV '70 041 with 1.65 rockers.

The Ram Air III was never a official designation used by Pontiac until 1970. The Ram Air numbers, other than the 1970 Ram Air III, the 1969-70 Ram Air IV & V were invented by fans. The Ram Air II was never officially named the Ram Air II but the name was mentioned in an internal service bulletin that mentioned the round port Ram Air motor was superseding the D-port Ram Air motor and the name was also mentioned in a print add. The offical designation for the "Ram Air III" in 1969 was still the 400 HO. The ram air equipment was included with this engine with the 1969 GTO but was not included with this engine in the 1969 Firebird except for the Trans Am. As mentioned in this earlier in this thread, the Ram Air IV was not named from it's preceived place in Ram Air development but was named after the proposed four place ram air system (two scoops on the hood and two behind the grill) that never made it into production.

Ram Air IV
Quote:
Here lets throw some thing else out there. The 1969 Ram Air IV was named by the amount of outlets that it was originally designed to bring air in from. Look back at the 1969 Lime Light Green press GTO's engine compartment. This is the GTO that later became the test magazine Judge. The air cleaner had two tubes running to the radiator core support, for two of the air intakes, along with two hood scoop air intakes above. Even though during the Ram Air III (Which is what it was called in the 1969 test) vs Ram Air IV. The article showed the Judges' four inlet air cleaner but called it Ram Air IV. Then the Ram Air IV Bobcat cars' air cleaner which did not have the core support tubes was used as the the III's air cleaner engine shot. Confussing? Since the air cleaner did not go into production and the print ads and media had been told this "new" for 1969 engine was called Ram Air IV Pontiac and the public bought into it. The early1968 Ram Air was just called that. Mcuh like the 1966 -1967. Just put a ram air tub on an HO motor. The round port that appeared in March/April at no extra cost was called 1968 1/2 Ram Air initially. Later in a few print ads it was called Ram Air II. The one that comes to mind is the 1968 Firebird ad calling it Ram Air II. I'll try and find some of those old ads too.

Ram Air V
Quote:
Unforunately PMD's new General Manager had his own ideas and the marketing people changed. With the change in direction at PMD the high compression 455 Ram Air IV head engine was cancelled. The low compression 455 first as a d-port HO was first offered then the following year it became a round port HO then SD. So, everything remained as we now know it. The Ram Air V is the Tunnerl Port engine no matter what cubic inch it is.

So the correction I could not change in the 65 minutes is: The 1969 article did not call it Ram air III but: "Judge vs Ram Air IV". Which I was trying to change. Sorry. Eric
