Nos l88 zl1 cam
 

In the gm tube perfect condition all parts numbers on cam and tube 895.00

I think you will find that those 2 engines used different cams. L88-"535", ZL1-"9181" Only other engine the ZL1 cam came in was the LS7

Add a set of 16 gm NOS mechanical lifters for 350.00 more.

I was under the impression that the 67-68 L88 used the "535" cam (1st Design)
1969 L88 used the 9180 cam (2nd Design) and was also used in the ZL1 and the LS7.

you are correct

Sometimes google search isnt reliable.
