Whoa guys, you completely missed something in the dyno results.
Look at WHERE the peak numbers happened! The Vortecs made a bit less pk TQ, but it was some 600RPM sooner! Personally, I'd rather have the 426 at 4000RPM rather than the 435 at 4600RPM. Don't just look at the peak numbers.
What this shows you is a more efficient combustion, which is obvious by the advanced design of the chamber. Hell, if you choose a cam that would make the peak at the same RPM as the camel humps did, the Vortec would definetely come out on top! Not only that, with the fast combustion, you can run more compression without detonation, which means even more power than the camel humps.
Sure, you could put in much $$ or hours into porting camel hump heads. But face the facts, it uses an old style chamber that doesn't compare to World Sportsman heads or Vortecs. Camel humps just aren't worth it anymore.
Porting can be done on the Vortecs. There are two areas on the intake that can use work, and the entire exhaust side can use some work also. More power can be had with the Vortecs.
I replaced my camel hump heads (that have large valves, bowl work, and port match) with my unmodified Vortec heads. I could instantly feel the difference, and my ET improved considerably. Both used the RPM intake, and I sold both the heads and the intake on ebay to break even on costs.
