Dears ,, I have LS1 with 5.3 heads and I'm planning to put good cam on it ,, so I found comp cam 54-000-11 which is perfect on different setups but on ls1 with is heads I don't know,,

Plz your advices

 

Are the 5.3 heads stock or no? What are the specs on that cam?

 

FYI, # 54-000-11 only tells us that this is a custom LS motor cam grind. It doesn't tell us what cam lobes are used. So you'll need to at least tell us the intake and exhaust lobe duration @.05" lift, LSA and ICL (intake centerline) for your custom cam grind before we can give you further advice.

 

sorry guys for the delay actually i didn't received the notification on my email , any way ,, i don't have the spec for the cam that i share it with you all what i did during my research is i found this link

so i just understand from your reply that it is not a standard cam it is depend my order ,, i thought it is a ready cam ,,

guys if there is any recommended cam good performance with my setup plz advice ,, i searching for a good one and im noop in this calculations

 

I wouldn't let Comp or Summit spec a cam.

 

That is a custom cam option meaning you pick the specs or let somebody else pick them. I would not let comp or summit spec the cam. There are plenty of shelf cams ready to roll that are proven.

What are you looking to for out of your setup? Street car, daily driver, or primarily track oriented? This is important information to know for choosing a cam shaft.

 

Call Kip at Cam Motion, Geoff at EPS, or Martin at Tick if you want a custom grind cam. Those vendors should also have some good cams ready to ship to you.

I wouldn't want a random sales rep from Summit or Comp designing my custom cam.
