I love the real lopey sound on a cam, and was wondering what the biggest duration and lowest lobe seperation angle I could go with on a 5.3L 4x4 to get a real mean lope but not sacrifice too much drivability? Its an everyday driver!

 

 

pull a spark plug. That will give it "lope"

 

Is it stock heigth? what gears do you have, do you plan on getting a higher stall, do you have any boltons

oh and the big question for any that are looking for cams HAVE YOU SEARCHED THE SITE?

 

pick you true rpm range or you'll be wanting to change everything else to match a mismatched cam

 

THIS AND EXHAUST, all the threads have been like this lately!

Wait, didn't you just post this 2 days ago?? --->"I am planning on doing a comp cam 220/220 on a 112 lsa, and was wondering which valve spring kit is going to last and perform well?"

Sounds like you already picked your cam, but FYI that cam isn't going to sound "lopey" at all...

 

You should just check different cam specs. If you don't see one you like have one custom made. Comp Cams website has a cam guide. If you don't want to lose TOO much low end go with an XR273HR 220/224 530/534.
They give you the RPM range of each cam so all you gotta do is get one that's in your range and has a good LSA and desired duration.

 

-212/212, .530", 108*
-215/215, .568'', 108*

Both those should have a good lope, and still have good low end. They are both ISKY lobes.

 

although I would be seriously worried about vacuum issues with a 108* lsa cam.
