More cars that don't exist!

Fridays post got some feedback and people wanting more information about "Phantom" cars-and why they do or do not exist. Here's some more. # 1. There are no LS6 Monte Carlos. I explained why they weren't in Corvettes in the previous post. The 454 was available in Monte Carlos, with either a Turbo 400 or a Muncie 4-speed, but it's the hydraulic-cammed 360 hp LS5. Rumors persist that at least 5 LS6 Montes were built, but I have never seen one, or a build sheet or a window sticker for one. The LS6 was sold as a crate engine until 1991, so I don't doubt that there are many cars running around with them, but factory installations were limited to 1970 and 71 SS Chevelles, a few SS El Caminos, and the previously mentioned 1100 or so 1971 Corvettes. # 2. The last "W30" Olds 442 was built in 1972. The "W30" package was introduced in 1968 on the 400 inch 442. It included an aluminum intake, revised heads and a hotter cam, as well as a funtional Ram Air system. These were grossly underrated at 360 hp. ( All that special stuff only gained 10 hp? The standard 442 engine was rated at 350! ) The option was continued when the 455 was allowed in the "A" bodies for 1970. These were also hugely underrated at 370 hp. Compression ratios were lowered in 1971, but other than that the package continued, rated at 300 net hp until 1972. The 455s were available until 1976, but they were generic "station wagon" engines-no hot cams, aluminum intakes,etc. After this, Oldsmobile shamelessy put the W30 moniker on any Cutlass performance package-the worst being the 1979 Hurst / Olds with a 180 hp 350 V8, and the 1984 Hurst / Olds with a 307 putting out about 155 hp!!  # 3 The last 455HO Pontiac was built in 1972. It was available in GTOs, Firebirds, and LeMans models. These awesome engines featured Ram Air IV heads and aluminum intake, special round-port iron headers, and the "068" cam-which was milder than the RAIV grind. In 1975 you could buy a Trans-Am with a 455 V8 and a 4-speed, that said "455HO" on the shaker scoop, but it was a "station wagon" 455 with 7.6:1 compression rated at 200 net horsepower. Only 857 were built.  The option was continued for 1976, as simply "455 Performance package" and 7,058 were built. The 455 was dropped for 1977.  # 4. The last LT1 350 small-block was installed in 1972 Corvettes and Z/28 Camaros. They featured "2.02" heads, forged pistons, a solid-lifter cam, an aluminum intake and a 780 Holley carb. Like the LS6, the LT1 was sold as a service replacement engine in short-block or long-block form until 1991, so you may see them in everything from Vegas to 4x4 trucks, but they were only factory-installed in Corvettes and Camaros. Hope this clears things up a bit. Mastermind
