Can someone help with this cam ID?

You may already have that cam.

Also, you’ll likely have a hard time finding one these days.
I'm just wondering if its too much cam for my build. Some of the reading I've done is saying that cam is only making about 9" of vacuum max. I need a bit more to run my power brakes. So, that is also weighing on whether or not I choose something else.

I just don't want to over cam. For reference, I have a 318 bored .030 with standard .030 replacement pistons. I talked to Wiseco a bit ago and I'm going to swap in taller pistons and likely have the block zero decked. I have a set of X heads that I'll be using and those are getting dropped off today to find out the size of the chambers. I have a 1900-2200 stall behind a 727 (change this to something else?) and currently running 3.55's but I want to put in 3.23's for lower highway RPM
