Detailed Description
Ram Jet ZL1: Part number not yet available
Getting a hold of one of these may be more difficult than hitting your state lottery. GM Performance Parts is proud to bring back a legend, if only for a limited time. The Ram Jet ZL1 is the ’69 ZL1 of the new millennium, with its revised aluminum block, a solid roller cam, large oval port aluminum cylinder heads, and the Ram Jet fuel injection system...that’s right, Fuel Injection. The Ram Jet ZL1 is ‘454 cid with a street friendly 10.2:1 compression ratio that will idle all day long, unlike its predecessor of the late 60’s. If you want a Ram Jet ZL1 get in line now, GM Performance Parts will be producing a very limited 200 of these all-aluminum Rat Motors for sale on the open market and I would be willing to bet Jay Leno already has his eye on one...make that 199!

This is old news, but yes, a nice package.
The total weight is less than 500lbs.
For $20,000, I'll buy another car.

Took them like 1200 hours to test and calibrate the fuel injection.
