You should make it unless your flight is delayed, or unless something happens with bags. I do this twice a month and rarely see long customs or security lines.
I never check bags and have global entry, so it takes me about 20 minutes from the time I leave the airplane until I get to my connecting gate. Most of that time is walking and in the security line.
