Go read mavns (gost cam thread) for a general idea, I thought it was pretty good results.

Appreciate the kind words

Nothing at all wrong with the ghost cam, and it's not a bad choice for the combination proposed. You have enough stall already, and that will make it very docile. I do think you'll have some idle note, but it won't be thumping by any means.

What actually caused me to make the smaller cam suggestion was the statement "I have no plans to upgrade heads". I was thinking in terms of dynamic compression to help with throttle response and midrange. Even with no plans to upgrade heads, if you could be coaxed to go to a .041" head gasket, both cams would benefit.

For comparison purposes, the stock '02 LS6 cam has -28 degrees overlap. The ghost cam will have similar RPM powerband as the LS6 cam, but should make more torque. The cam motion cam I think will make more torque than both stock and ghost cam, but mainly due to cylinder pressure (dynamic compression). The cam motion cam will fall off faster up top, and the ghost cam will carry better, Around 6300 rpm, I think is where you'll see the ghost cam really pull away. So a lot depends on where you tend to or INtend to shift. If your plans are to stay below 6000 for the most part, I think you'll be happier with the smaller cam.

I don't think you will be unhappy with either choice. You will probably want to pick up some psi1511 springs, retainers, shims, and a pushrod length checker. Plan on ordering a set of 5/16 pushrods.

Summit 8715 Ghost Cam .

I have a huge thread on it .

Works well n/a, and boosted, and would work fine with nitrous. I'm going to stick one in my ls3 c6 here soon .

See this is why we listen to darth lol.

I had mentioned thinner headgaskets earlier as well, partially cause I like the idea of replacing the lifters.. and doing a little upgrade on them and the head gaskets all in one deal, plus those lifters are likely to be original which puts them at around 20 years old. Steve Brule said he's seeing a lot of lifter issues and has run some tests recently on older OE lifters vs fresh basic aftermarkets and is seeing 10-15 hp pretty easily from just running a little better lifter. So what do you think about the basic morel lifter 6504?

I had a 222/228 114 cam and with ac on it was pretty tame but had some chop with the ac off. Not sure by what you mean in regards to a sleeper cam. The rough idle is a symptom of overlap and overlap is what helps make power up top. You can look at high lift truck cams for a nice idle and good low end torque and response, they just wont pull as hard on the top end.

I like the idea of doing the head gaskets and lifters. Both are stock and have never been touched.

Thanks for the suggestions on the Ghost cam guys. We think it would be a great fit for this combo. It's the SUM-8715 with specs of .600/.575, 222/233, 113+3 with -3* of overlap. This will have that stealthy idle you're looking for but pack a punch. Your mods with the addition of the LS6 intake will pair well with this cam.

You’ll need some better springs. All of our Pro LS cams are offered in combo kits. We offer them as cam and spring kits or cam, spring, and install kits. View the available kits here for the Ghost cam.

Different pushrods will be required. We would recommend a minimum of a 5/16" .080" wall. We typically find a 7.425" pushrod will work with the Ghost cam. This isn't always true as there are possible variances. This is why we always recommend measuring pushrod length before ordering pushrods. We offer the TFS-9501 pushrod length checker to do so. You will need a set of 9" dial calipers as well to measure the pushrod length checker.

This was a very informative post. Thank you.

I'm going to throw a wrench into these plans a little bit and am looking for some insight. I am now willing/wanting to do an upgrade to the heads. I dont want to spend a fortune. If I ran the ghost cam, what would be a decent set of heads to combo it with? Or would you suggest something different entirely for a cam too? Again, I really don't want a big choppy idle.

I think your ideal heads would be a set used AFR205. The old ones. Something with a tiny port and crazy airspeed.

You are going to get a bunch of suggestions for ported stock heads. For what you are doing I would not go that direction personally.

Mavn's 450+ whp Ghost Cam Build with TEA S2 5.3 ported heads might be an interesting read if you've not see it.

Most aftermarket heads are very close in power production. If you have a set of ls6 heads on you, port them from Total Engine Airflow. If you dont, TSP makes 225 as casts for 1700 bucks that work very well and I made a lot of power with them. Then you got your AFR/Trick CNC heads which are at that 2200 price range and you dont gain much from the previous options. Then you got small bore mast heads which will make a ton of top end and loose a little bit down low and more for the 7000+ rpm peak guy.

When it comes to cathedral port heads, get a set of 243 run 'em stock or ported and you are good to go.

Tyler Dietzenbach

I can probably get a set of those for next to nothing. You think they're good enough?

G Atsma

If they're in good shape, yeah. 243/799 heads are the best factory cathedral heads.

243's would be a nice cheap upgrade

Or send a stock set out for porting

TFS as cast 220's are some of the best for around $1700, and TSP as cast heads. The prices go up from there.

The ghost cam, the 243 heads, stall etc should make you an easy 11 second car and be a lot of fun.

What's your acceleration goals tyler?

SoCalDave

Yes, a set of 243 heads or 799 heads, once they are ported will have your combo making some solid power numbers. I did a lot of research and 243 heads and 799 heads are the castings that consistently get praise for making power.

Thanks for all of the above suggestions and comments. I really appreciate them. I would be plenty thrilled to run in the low to mid 11s

Easy enough for a cam only car.. Have you ran the car as it is?
