Cam 5.3s making over 330+hp
#21
I know its been done past 330RWHP on a NBS 5.3L, stock 862 heads, stock intake manifold, and a NON HO engine. Its hard to find actual dyno sheet with all those stipulations on your OP though lol. It wasn't much past the 330 mark though, I think it was 341RWHP and IDK what dyno it was. The video might be on youtube.
I think it was a 224/230 .581/.588 112 lsa cam also.
Your buddy is correct though, the normal is about 330RWHP. Every once in awhile you will see a 335-340RWHP as per your OP. Some people have those "Special" trucks that just dyno a tad higher than everyone else also. Maybe they were made on a certain day haha who knows, I am sure you have herd jokes about that before.

Thanks Cajun, i was waiting for you to chime in hear! lol
Sure most 5.3s don't dyno over 330hp... thats because they put small cams in them and aren't tuned correctly. There's proof right there that even a 220 can make over 330. For the guys with the 230 duration cams with lift close to .600 I know that with the correct tuning their trucks should be on up there.
