Yes. 1967 - 69 received the 302ci engine.
This is an excerpt from the CRG site:
Q: Why was a 302 motor available for the Camaro Z-28?
A: The 302 engine was only available in first-generation Z-28s (the 350 LT-1 was used in 2nd generation Z-28s), and was created in response to a Trans Am racing engine displacement limitation at that time of 5 litres (305ci). The 302 was created by installing a short-stroke 283ci engine crankshaft in a 327ci block, resulting in 302ci. This just fit the Trans Am limitation (the bores of the actual racing engines were tweaked to produce exactly 305ci) and this design (with special modifications for high-performance use) resulted in an unusual, high-revving engine that helped create the legend of the Z-28. The 302 was the only engine available in the first-generation Z-28.
