Intake
I agree. Not too many RAIV owners swap over to fuel injection, but to each his own I guess.

I just noticed your location. I grew up in Falls Church and went to McLean High School for two years before moving away from the area. When I was attending McLean HS, there was a '68 or '69 GTO on Sea Cliff Rd heading into the school, that I had heard had a 428 in it and was quite fast. I only saw it driving a couple of times. This would have been in 1972-1974. I'm not sure how long you've been in the area, but thought it would be cool if you knew of that car.

I grew up in Falls Church and went to George Mason HS. I don't remember that car, but a friend of mine in high school had a Matador Red 69 4-speed Judge. His dad surprised him with it on his 17th birthday in 1981. It was a super nice car.

Oh, interesting. George Mason was very close. I lived off Idylwood Rd. @ Route 7 with the only thing between us and Mason was a lot of empty land that we loved to explore. I know they've since extended I66 and Metro station on that land. I've always wondered why we didn't attend Mason since it was the closest HS. My brother went to Marshall and I went to McLean. I haven't been there since 1979.

His came from that area of Virginia (where he bought it 15-20 years ago) Matador/Parchment/ Ram3 / 4spd /Hideaways #'s matching drivetrain Does that match the High School car ? He restored it years ago and it's probably the best color combo i have ever seen for a 69 Judge. Red-Black-White decals and Redline tires. Everything compliments itself in perfect color-key coordination front to back |

BVZ - That must be a different car. My friend's car had fixed headlights and black interior. His dad had the car repainted before he gave it to him on this birthday and it was an amazing car. It was super powerful and tight with great paint and interior. And my friend never really drove the car hard. We were always trying to get him to tach it up and lay rubber and he wouldn't do that. I think he was afraid what his dad would do to him if he wrecked it.

What would have a prototype alumunum SD455 intake have looked like?

Carries a different part number than any 69-72 aluminum intake and was made available over-the-counter. Numerous PY'ers have owned them. But i forgot the part number Been some pics posted of them in the past They used to pop up on eBay once in a while Thought pattern consensus is they went into service parts category when SD had to have EGR by the time it was released into production.

That would be the 485640 intake.
Timing for production dates is correct and the part number fits into SD455 development phase.
Later it was sold over-the-counter as a replacement 455HO intake. And, like BVZ, consensus is that the need for EGR killed its' use on the SD455. Too bad...... |

The old Pete McCarthy Pontiac Musclecar Performance book shows the intake as a 1973 "Non-Production" unit. Same book shows the cross-over p/n as being applicable to 69-71 (Ram Air IV/455 HO). 72 cross over was p/n 488983.

In this case, Pete was wrong. There aren't many mistakes in his book, but that's one.
The old-school thinking was that the #485640 intake actually made it onto production SD455 engines, when, in actuality, it was probably used on the developmental and 'pre-production' engines only.
Now it has been pretty much accepted that the intake was designed for the SD455 project, but the need for an EGR valve killed it. Other than the casting number, it's pretty much identical to the #488945 1972 455HO intake. |
