Cam question
#41
I think now I will probably leave the lifters and use the 5w30 you guys recommended, I almost bought it once but didnt know if it would be ok.
and now that I look at my water pump, it does look like it could be seeping somewhat, because its a little wet/dirty looking and lts not oil. So I will probably stick to just doing the cam, z06 yellow springs, and some pacesetter LT's.
Now my only remaining questions is: should I replace the pushrods, or are the stock ones strong enough?
Are there any other extra little things I should do or add while I have it apart doing the cam and headers?
What if I found a used cam with real low miles, should I consider it or buy new? I figure it might be ok since its all roller lifters
I highly appretiate all your guys help and opinions, it has helped me start learning more about the genIII motor, since most of my hands on experience has been on my 67 camaro 350ci and my jeep cherokee 4.0L

I'd definitely do pushrods, cheap insurance IMO and the stockers can flex and bend at higher RPM's. Guys have run the stock push rods without problems, but I wouldn't recommend it myself, just my opinion. Many folks run used cams, as you mentioned, since they are roller lifters, they don't really wear much if at all. Keep your eyes on the classifieds here and you may find exactly what you're looking for

If it were me, I'd go bigger...I'm currently considering a 220/224 or a 224/230 cam for my LQ9 (if I can ever afford to put it together lol). These grinds are considered mild by most guys' standards for a 6.0
*EDIT* I just noticed the lift and big tires in your sig...something else to consider when you're choosing your cam...big duration cams and big tires don't usually play well together, as you usually want a bit more torque down low to help to get those big meats turning

You could use that cam if you wanted to, it wouldn't require a converter in a 6.0 and would have a low torquey powerband. If you're looking for more midrange and top end, go bigger of course!
Just be sure to match the converter and gears to the cam you choose. There are guys running 6.0 cams that range from your current 212/218 on up to cams in the high 230's in duration, it all depends on what you're looking for, what you consider "daily driveable", and how concerned you are with fuel economy.

should i just move op to the higher lift version of this cam? or should i re-think it and pick a new cam all together? I drive it almost daily, but for what i want to get out of it i am leaning more on the performance side than the fuel economy side. I want it to sound like it has a cam but idle decent as well.
I also plan on having blackbear retune the pcm and soon down the road I plan on getting some full length headers (pacesetters)

I have a 212/218 on a 5.3 and it's perfect for a DD, I'd choose a bigger cam for a 6.0.
Read this thread, the guy went from a 5.3 to a 6.0 with a similar cam, dyno sheets and all.
