I've looked around and can't seem to come up with the spec for the
base circle diameter for the stock LS7 cam. My new cam is 1.462, that's straight from the tech peeps at Crane Cams. He told me not to expect GM to help me with this so I'm going here. Trying to figure out pushrod length the easy way. Put in 7.750's, kind of noisy.
Anybody know this one?
Thanks

Get a pushrod length checker, or measure your lifter preload. IIRC LS7s want about 0.050 preload.

Been there done that
Just not working for me.
I think if I get the stock spec I can just do the math??
Maybe?
