Re: 69 L72 CAM
Bill,
In Karl Ludvigsen's Corvette book both the '65 L78 & the '66 L72 were rated at 6400rpms.
However the later engines such as the '67, '68 & '69 L71 which also was a 11:0 to 1 compression rated engine, did indeed rate their 435hp at 5800 rpms. I don't know what rpm's the '70 LS6 used for their factoring with a 11:25 to 1 compression, but the '71 454/425hp rating was also rated at a low 5600 rpms, and this with a factory compression rating of 9:0 to 1.
