I remember reading about the "ZL-1 crate engines" several years ago (early 2002 I think). Back in Dec 2005 Hot Rod built a Camaro using one of the new 69 Camaro bodies being released by a company called Dynacorn (I think Year One offers them), and they put one of the ZL-1 crate engines in it. Back then they were saying only 200 were going to be built, and oh by the way, for some reason they weren't 427 cubic inches - they were 454. GM part number was: PN12370850 and they were about 20 grand to purchase.

I owned a L-89 Vette back in the late 70's. -No where near as radical as the L-88, and marco was right, the L-88 was a lot more than a $1000.00 option. The L-88 Vette really wasn't meant to be driven on the street - cam was WAAAY too radical. No air, no radio, no creature comforts, and a cool cowl induction hood (which I bought and had on my L-89 car). I also owned a LS-6 Chevelle in the 80's. The LS-6 was a monster of an engine which could easily be made to produce even more power. The LS-7 was a hoped up LS-6 but was never put into a production car (as jwd stated above).
The alum ZL-1's were basically L-88's with an alum block. 69 COPO Camaros had them and the cost of the engine option was almost as much as the cost of the entire car. These are million dollars cars today, and the ZL-1 Vettes fetch even more (in fact, I think only 1 out of the 2 made exhist today).

Also, just for the record, no Corvettes were ever sold to the public with LS-6's (or LS-7's). Chevelles were the high HP cars in the Chevy lineup in 1970 - not the Vette.
-What a advertising bust Chevy went through that year!
