Sooo....by my math that's about 660HP at the flywheel!
Pretty dang good, I'd say!

Bad news - it was making some lifter noise before the Dyno. I think one lifter has let go. Will pull the heads and inspect. If lower end looks good probably will upgrade heads/arp head bolts and a couple other things. If it is a piston problem I’ll scrap the 5.3 and build a 6.0 and shoot for 700 hp.
