I agree with Kenth.
I tore down a couple of 1968 350 HO engines in 1970 (when at the university) and one had the 066 camshaft.
We had a class on Engine Design & Assembly and were required to disassemble the engines, take measurements, reassemble the engines, and run them on a engine test stand. One of the engines (for the class was donated by GM Engineering and was supposed
to be the 350HO engine). The second engine was owned by a friend and installed in his Firebird. He later tried to run a RA-IV
camshaft in that engine on the dyno, (posted about this in the past), and the engine was a dog throughout the rpm range.
Neither engine had the 068 Camshaft installed right from the factory.
The 068 camshaft was a very nice camshaft in the larger 389 and 400 engines.
Just my experience on the subject.

The dyno engine even had aftermarket pistons installed before the dyno test (except that the pistons were made with the wrong bore size/clearance and seized in the block). Posted about that too.
