Ls3 c6 build questions Never really messed with LS engines or OHV engines. Few questions I have come up with as I try and plan out what to buy.
Ls3 in a c6, planning on these engine parts
Cam (unsure yet, was planning to talk to Pat G, or maybe BTR as to specs. Want fairly big 230+ duration Id think. Rough idle within reason isnt an issue. Open to suggestions)
GPI ported ls3 intake
Cai
1-7/8 headers to an ORX
NPPs
Hoping to get close to 500rw, it is a 6l80 so if I get 475 I'd probably be happy. Want to run a 10 at the track. Ive seen a few cam cars at or around 500rw so its doable. Stall convertor is in the works probably soon after the cam.
Other questions I have.
Car has 120k, I assume I should do the oil pump while Im in there? Probably just a stock replacement.
If I do the oil pump, I'll do a timing kit so I might just convert to a 3bolt cam. And probably convert to a ls2 tensioner.
What should I do for top end? Convert the trunions to roller? Buy new?

Not as interested in the max effort bolt on as he is, though the car is very impressive. Id be happy to make about the same rwhp as his roller rocker only car. Curious if Hio is still porting ls3 intakes. I think he was doing them?
Curious how the 4.10s would do in the a6 as this is much more of a driver than his car seems to be.

With a sbe and auto he can get by with more cam....... He can gear the **** out of it and take advantage of 8200 rpm if he chose to. IMO the goal of 10s in a c6 auto is a cake walk with stock cam. You dont even have to get stupid with the build. You could easily do a cam as Darth suggested and be way ahead of these large split cams and keep the car in a 68-7100ish shift point. if your doing this with stock wheels and drag radials itll be a bit more challenging. You can do all the basic bolt ons (keep the LS3 intake and rod mod it), add electric water pump and crank scraper to the mix and good set of psi1511/1516 springs with 11/32 push rods and dance with the 10s. This car has 120k miles, me personally I would pull the heads and swap lifters, mill .040 to give it a little bump in compression and use some .041 gaskets to ice the cake. You put on a nice drag pack and drop 80-100 pounds of rotational weight and there is the mid 10s (as long as hes in a decent DA situation 2000 or less).

So many viable options, so many ways to skin the cat.
Not sure the stock cam route is the way to go for me. I dont do much street/grudge stuff as I used to so the sneakiness doesnt do me much good.
Its mostly a fun driver that will continue to walk my friends to keep them motivated and improving their cars. Me running mid 10s would mean theyd need a serious shift in where theyre aiming. Other than, that just drive it, do hoodrat **** occasionally, scare my grandma and my girlfriend.
The cam doesnt need to be super radical, but a healthy chop makes me happy to hear it and the auto means the cam wont be so bad to live with.
If I decide to go fast in the future, I'll just snap on a d1 or novi and swap the cam. Make 6-700 and run single digits.
Itll run at the track on a drag pack probably, but will live on a 19in street tire.
Like I told lazer in PM the most gear its likely to get is 3.54s. More likely 3.15s. Can you regear a c6 diff like a normal axle/3rd member? I never see anyone talk about doing that. Just buying new.

Hello ShelbysGuns,
Sounds like a fun build! Our nasty LS3 camshaft is the Titan King LS3 Cam, This camshaft has a wicked sounding idle and makes great midrange and upper RPM power. It is the perfect match for your goals.

So besides just the cam does anyone have input on what else I should do? Standard ole pushrods or hardned/lightened. Do I need to upgrade the rockers? I hear bad things about the comp cams trunion upgrades what about the tsp already upgraded ones? Should I just go YT rockers? As I said never messed with Ohv stuff, bought that ls2 car as it was.
I assume at 120k I should change the oil pump. Hear widely varying answers on stock repalcement or melling.
Also any reason I should go 3 bolt? Unless the cam I decide on is 3 bolt only.
Would really prefer to leave the heads on and alone for now. I already have one project that has spiraled out of control and sits non running. Dont need two.
