We've done several camshafts in that size range in 5.3l engines. You need to be really careful, you'll defiantely need some extra stall to get away with a camshaft that large. We sell a lot of the 216/220 camshafts for customers trying to keep more low end power in the 5.3l engine. You might also consider something custom cut off our lobe selection section of the site. Here's a link:

From here you can custom spec your camshaft & we can get her cut & shipped to you!!
