How will it perform?

Pretty sure you saw my cam card for my Racer Brown cam if you want more duration. He made this cam for a friend of mines street car. I’d like to try more lift one of these days.
Yes, I have that cam card saved in my notes. I bounced the idea of more duration with my cam guy (same guy that sent you the Victor 340) and we talked about the specs on your cam card but eventually he talked me into trying what he spec'ed out first. Easy enough to change cam down the road if I am not satisfied with how it performs.
