In the GM Perf. Parts catalog it says it has a lobe for a mech. pump. I have the hot cam installed on my engine and just went and looked up the pushrod slot for the pump and it looks like theres a lobe for it.

I had the Hot cam out of my LT1 a month ago and it does indeed have a fuel pump lobe. I guess it was for people that wanted the cam for non LT1 use.
