Here in Cincinnati there was a dealer called Henry Sieve Pontiac who Bought 38 Ram Air 5 motors through the parts Dept..25 of them went into GTOs/Judges installed by the service dept..If that many Ram 5 engines was bought by one dealer alone there must have been alot more made than 250...And these engines where monsters on HP..People who claim they flew apart at 6500 RPM NEVER drove one or Dyno one or even seen one run...And the last one sold was in 1972...I tried to buy one in 1973 and they was out of stock...And just how many went out the back door at pontiac by employess ?

I don't know how this 9+ years old thread resurfaced, but......I was working in the Pontiac Engine Plant 9 and Pontiac Engineering in 1968-69. I was involved with some RAV engines used in NASCAR. I can assure you, contrary to the "spec data" shown above, These engines were hand grenades if you ran them above 6500-6700 RPM for more than a few seconds. I can also document that the last four of the 400 CID RAV crate engines were sold out of GMPD in 1974 to one individual. One of those was campaigned in an ARCA short track race car in Michigan for about 1 1/2 years.

I was a teenager in the Detroit suburbs in the 70s. I had a friend who's dad was a Pontiac employee (I can't recall what Mr. Poole did there). The father had a 428 Ram Air V and put it into a 69 Firebird and gave it to his son (my buddy) after Dave had 2 minor wrecks and getting in trouble with the Royal Oak PD his Dad took it away from him. That Firebird was wicked fast and was a handful to drive. Throttle steering it was easy, and it was a high revver. It also had manners under 4000 RPM. Above that it acted like a turbo kicked in! It was WAY too much car for a kid- but in those days lots of guys had one off stuff from the big 3 so it wasn't rare to see amazing cars in the tawney suburbs high school parking lots.
I was in a machine shop in Detroit in '78 looking for a special 289 part and the grungy kid working there showed me a 303 CI Ram Air V head. It looked like a FE tunnel Port head but the push rod bosses were cast not steel tubes.
I had no idea I was in the midst of the greatest years of Detroit muscle then. It wasn't until the abortions of 1977 on became the normal turds from Detroit for the next 30 years that I realized just how special those days were. "Too soon old and too late smart"

Tripped across this page and thought I'd share some info about the RA-V engine production that I got straight from Jim Wangers, Milt Schornack (of Royal Pontiac), and various Pontiac engineers from back in the day for magazine articles and book fodder.
Hopefully this helps clear up the confusion.
The RA-V was developed in 3 sizes: 303, 400 & 428. NONE were ever installed in vehicles on a production assembly line. Not even in Canada.
Super8 is correct: A few hundred 303 crate engines were built ... in an effort to certify the engine for SCCA Trans-Am series use.
At least 29 400-inch RA-V crate motors were built for sale through GM Parts Div.
No one that I've spoken with knew of any 428s that were built and offered for sale.
But Mike Ornellas is correct about the test mules: several were built (unknown number). At least one documented 428 RA-V test mule GTO exists in North Carolina. (I know the owner, but keep that info private.) And last I knew, the blue/white RA-V car was in Michigan.
But, basically, while the Ram Air V program was intended to go into production, it never made it further than the crate motor stage. Again, NONE were ever installed in production vehicles on a Pontiac assembly line. All cars -- including the test mules -- were hand-assembled in engineering garages or (as Super8 pointed out) by Royal Pontiac ... or anyone else who ordered a crate motor and installed it in their garage.

OK Super 8 genius.
You need to do some more reading.

The blue Pontiac from pic below is one of the 4 Royal Bobcat Ram Air V car that documented. There's a Royal Bobcat badges behind the car and the hood has Ram Air V badge near the vent.

I know this page is old but I just found out something new. Pontiac build 250 Ram Air V but only the engine. Most of them gone to racing and the rest is brought back to factory to be stored or destroy. Only 4 street car that documented and survive. All of them are factory option from Royal Pontiac and badges as Royal Bobcat car. Some test has been done by Royal Pontiac including the 1/4 mile. Fastest 1/4 mile in standard condition is 12.6 sec @ 109.52 mph but it was done on windy and cold day. On normal weather, it can do faster than that considering Ram Air V had 500 hp. It's only available for 1969 only because in 1970, Royal Pontiac didn't want to touch performance thing on GTO because they think it's enough. But, it can be ordered from dealer and fitted to GTO thought.

I never even heard of this version of the Pontiac GTO, Ram Air V, I expect way less than 250 of these were built, like mike ornellas said, only a handful.
mike ornellas 9y ago
Actually GM made a hand full of test mules with a V motor in them. Executives were able to test these cars on the back lots of PMC.

@ 421 SD: Nope, you're wrong! Try to read this! http://en.wikipedia.org/wiki/Pontiac_V8_engine#Ram_Air_V
It's available as crate engine after 1970.
421SD 9y ago
No Ram Air V engines were installed by the factory in any body style. These engines were only available as crate engines or parts.
Do your research before opening your mouth or posting comments.

It's unknown how much Pontiac built this GTO but i think it's less than 250 unit just like Firebird Ram Air V

This is the rarest Pontiac and fastest Pontiac GTO in 1969 to 1970. It has max redline up to 8000 rpm. Very good for top speed run on NASCAR track but useless for drag race. Because of that, none of this vehicles fitted with close ratio. All of them fitted with long ratio 4 speed transmission.
