Please help 68 SS 427 #s match?

[COPO_Anders]

As far as I know at least three of the -68 Yenko Camaros got their 427 engines at the factory. Two all iron L-88 cars and one L-72(the "Heath car"). All documented in some way.
Aren´t they considered to be "pilot cars" for the -69´s to come ?

The Heath car is an interesting one, I've talked to prior owners of that car who laugh about the engine part - it had several engines before the 'One and Only on the Planet' giveaway. The common belief is that there were indeed no proven 427's installed into the '68 Camaros. The pilot car situation is the closest one, but we don't know the vin # of the paperwork for the pilot car!

I won´t argue with you Marlin, since I have only read about it in two articles, from 1996 and 1997.

It says in one of them that all three Yenko Camaros, one white in Illinois, one black in Indiana and one light blue metallic in Colorado, have some sort of documentation.
Heath found a broadcastsheet in his Camaro it says, and that made Chevrolet investigate if it had been built with a 427 at the factory.
The other two all iron L-88 cars still have their protect-O-plate according to the article. The engine code is said to be MV.

Has it been confirmed that none of this is true ?

The "All Iron L-88" sounds wrong to me? A L-88 came with alum heads..! NO..???

True !
But if you for some reason don´t want the aluminum heads, but want the power from the L-88´s cam, pistons, intake, carb etc. Then you put iron heads on it an get an "all iron L-88"

I believe the last -71 LS-6 Corvettes were sold with iron heads for 600$ less, and they were still considered to be LS-6 cars.

Yenko liked to build iron-head L88's for customers, so that is where that reference comes from.

To my knowledge the white one from IL in that article is the only one that might be a 427 factory install, it has some unique badging that might indicate it being a prototype. The way the got around the emissions requirement for the 427 factory install in the '68's was to list the car as an 'export' - pretty slick!

You are missing the main point that the L-88 was never offered from the factory with cast iron heads. That would be something a dealer would have to change after the car was delivered. It would make a large difference in the value not to mention the originally of a car.

What happened later with the LS-6 was a factory thing. The value of the car would still be there either way the car was "Delivered" from the factory.

[COPO_Anders]

I wasn´t thinking about the value at all. I was trying to describe the engines. And since there are no L-88´s with iron heads from the factory there is no other L-# I can think of to use.
And of course the magazines used the phrase "all iron L-88".
