Base Cirlce

I'm trying to find the base circle of an LS6 cam. I know the LS6 is smaller than the LS1 but I just can't seem to find the exact number. And for that matter, the LS1 either.

Any help would be appreciated. Thanks.

From Thunder Racing's website :

LS6 Camshaft - 204/218 .551/.541 117.5 LSA Please note that this cam has approximately a 0.050" smaller base circle than a stock LS1 camshaft. This smaller base circle will require longer pushrods for applications with stock length valves and no milling for the head surface.

base circle

I remember doing a search on the internet for ASA cam and I ran into an interview with some GM engineers who discussed the base circle of the LS6 versus the LS1 cams. I believe they referred to specific dimensions. Maybe this might help.
