Default Comp 265 High Lift cam???

Was looking on some feed back with this cam for a 5.3L

I was thinking about have something similar ground for my daily driver. I wont be racing it. Was gonna use the 265 Low lift version but after ridding around In other trucks I think a little extra lift wouldnt hurt.

Stock rebuild 5.3L with stage 1.5 heads from WCCH.
I have a 4.10 posi and a 2600 stall with a new 60e waiting to go in.

I was looking to go with somthing like
212/218 575/575 ground on a 114 with 2 degrees advance built in.

Not looking for a lope and Not looking to be the fastest. more of a low to mid range Gain over stock and of course a little more out of the top end too...

Any reasonable tips or advice???

Thanks in advance

Seems like a ok cam to me too, but with your ported heads you might be better off with Comps newest line of LSR cams. Ive always like their new 215/223 .604/.610 112 LSR cam.

I run an LSR cam myself (219/235) and love it. Im running 918s with Tool Steel retainers. If you wanted duals go with the 926s with tool steel retainers.

I'd run the low lift version so you can get away with LS6 springs. They are way cheaper and will have better life expectancy. I would for sure wanna have a good converter with the cam. I had the low lift with a TB stall and I was terribly disappointed in the low end power.

Yep, that ought to be a good stick in a 5.3. I'm running that same cam on a custom grind, (212/220, .560 lift, @ 114) in my lq9. Not too much lope after it warms up, but still noticable. Ran real strong down low and pulled hard all the way to 6500, while I was NA. It works even better since I put the tvs1900 on it.

I think the low-lift is a better all around performer. It isn't just a difference in lift values, the valve events are entirely different between the two, and there's quite a few dyno graphs around that show the hi-lift version losing bottom end grunt that is so famously associated with the low-lift version. And, as was mentioned before, you can use the economical LS6 springs with the low-lift cam.

Yes I read that Thread. I already have that cam installed. I dont want to get into the specific details But lets just say I can have any cam I want.

I have PRC dual Gold springs so Lift Is not an issue. I could swap them out for the Yellow LS6 Springs But I would rather leave them alone.

I have no problem with the low lift version of that cam, I just figured I could better maximize My over all package with a little more lift. I can have any cam specs I want ground so I wanted to get something that would work well with this package in a daily driver application.
