Like what marco said. I think chevy built about 30 L88's in '67, and about 120 each in '68 and '69. They had 12:1 compression, a bigger cam than the 427/435 cars, and with headers, put out about 550+ HP, but rated at 430, as I read, so the "rich" kids wouldn't check off the option unlike the 435HP engine which was more streetable. The ZL1 was actually like a 69 L88 but with the aluminum block. L88's had I think different heads through its evolution, initially closed chamber, then open chamber, and I think the cam got more radical as well, culminating in the late L88 / ZL1 specs.
Basically a factory race engine, kind of like the new Z06.
The L89 was basically a 435HP motor ( ? L72) but with aluminum heads, same cam and other engine parts.
