Yes that is a moderate cam in a 5.3 and would work great with about a 3k stall. Great stall for a DD or mild truck.

im runnin a tr 220 cam in mine with ls6 springs and ls7 lifters. 3000-3200 stall FTW

Red truck on that cam but lower lift has gone 12s now... With stock gears I went 13.6 3200 stall.
