Good luck Sleds. The best bang for the buck I eve found were the HO cams.

 

I just did the HO cams and the 08 intake. I am using superchip, but I still got a lot more top end. I still have the underdrive to install.

 

I'd be a little weary of the UD Pulley, some have gained a broken crank from em.

 

Broken how? As in broken crank bolt? I can't see how this would cause the crank itself to break...Enlighten us, lghtngblt02!

 

I thought the pulley became out of balance because of a manufacturing error. I thought BadassRT or Superdak05 had one on his and cooked the engine. If you search his old posts, you should be able to find the thread. I know they ended up getting the engine replaced under warranty, but it was infact the pulley that caused the issue.

 

The end of the crank broke causing the timing chain to pop off and then **** ran downhill...

The engine wasn't covered under warranty because of the UD pulley being installed, all he got out of it was a refund from ASP on the pulley and the cost burden of a new engine. They said it was installed with a long bolt thus not tightening all the way, ie user/installer error. I just dont see the benefits on a mostly stock engine where the gains are so minimal and the charging issues maximized along with the added end stress on the crank. It doesnt make sense to me.

 

do you need lashcaps to go from the 4.7 cams to the 4.7 HO cams? and if so what lashcaps are we to use, need answer quickly doing swap in next 24-48 hrs

 

Same caps as stock cam.

 

Don't need lash caps I just got done installing my HO cams.

 

I replied to your PMs. HO cams are a direct swap. You won't need lash caps until you start looking at 206 and bigger regrinds.
