I'm undecided between the Summit stage 2 or 3 turbo cam. I have read a lot and seen a lot of videos of people saying not to over cam. I'm sure I would be happy with either one. But, what will the engine be happy with? Going in a 66 Chevelle street car. Don't really have a power goal in mind. Just whatever it makes is what it makes. Thanks!

Where do you REALISTICALLY want your power band? The lower, the smaller the cam.

Kind of what I'm thinking.

I have the stage one summit cam, ghost cam. Its responsive right off idle and it pulls to 7000. fwiw.....222/233...plenty big enough to make big power.

I have heard nothing but good about this cam. No negatives! Have we found the best all around cam?? LOL
Summit struck gold with this one... cam engineer needs a raise...

You dont want to over cam the little 75mm turbine anyways, its already going to be stressed with a 6.0.

Agree the ghost cam is plenty to run 8's and be a great all around driver.

Keeps pulling past that too!

Facts, I can't seem to find anything wrong with it.

yep!!

So, by the last few posts. It sounds like don't get the stage 2 turbo cam. Is the VSracing 7875 next gen billet that limited on 6.0? If so, I can always get a different turbo. I thought the next gen billet was good for 1000hp.

Usually closer to 900 on kill with a 5.3L. What are your goals?

Ghost23

I don't have any HP goals. It's a muscle car and I want it to have muscle. Not all that worried about having a good daily driver. That's not what this car is for. Its not a drag car so I don't care what it might run. It's not a car to see how much power it makes on a Dyno. As long as it runs, sounds good, and doesn't blow up when I hammer the throttle. I've heard the 7875 will be instant boost. Which is cool. But, then a lot of people say it will run out on the top end. I have this turbo because I got it for a good deal. Was looking at going bigger. Which I still might do. If it makes 700 it 750 and sounds good, I will be happy. Was looking at the stage 2 cam just in case I wanted to go bigger in the turbo. Never even thought about the stage 1. I will have to check it out.

If I was to step up from the 7875 next gen billet. What do you guys recommend? A bit of lag is fine as I see that as traction control🤣 Honestly it doesn't matter what this engine makes down low or top end. I know it will be much more than the 355 that's been in it for 23 years.

Next step would be the 80mm, I’ve made ~1025whp or so with those.

good to know. I just got one to install in my LY6

I also just installed this in my 347. Can't wait to get the car back together and ironed out.

OP have you watched Holdener's video about turbo cams?

Ghost23

I watch all of his videos. Have for years.

OP,

The community has provided some great advice here. We like where folks are going with this.

As fellow members have stated our SUM-8715R1 known as the Ghost cam would be a great fit here. Specs on it are .600/.575, 222/234, 115+3 with -2* of overlap. It'll have a smooth idle with it turned up around 900. Turn that idle speed down and you can get a noticeable lope out of it. This cam is easy to tune with excellent street manners. As other members have stated while it may be mild-mannered you can turn the wick up to 7,000+ RPM. That's with the popular PAC 1218 beehive which we carry through Trickflow as TFS-16918-16. For those that like added insurance, we offer the .660 lift TFS-2500286 duals as an upgrade.

To give you an idea of the idle of the Ghost check out the video below. This is fellow member @Kfxguy GTO when he still had a 5.7 LS1 in it.

Here's the same cam in another 5.7 LS1 that isn't so subtle. This just goes to show that every application is different and you're not always going to get the same sound.

The stage 2 Turbo cam you originally posted is another good option. If you want something that has some bark behind it this would be the ticket. After all this is going in a 66 Chevelle. This is SUM-8706R1 with specs of .600/.575, 226/230, 113+4 with 2* of overlap. It has a nice steady lope but it tunes well and is easy to live with. This moves the RPM range up a bit from the Ghost cam. It'll be plenty happy to spin to 7,000+ RPM with either of the previously mentioned spring packs.

So what does the idle of the stage 2 Turbo cam sound like? Check out the video below. This is in a 6.0.

Here's another example of the stage 2. This is in a 5.3.

We know our customers like combos to make these cam swaps easier. We put together a variety of combos throughout the PRO LS cam lineup. To see the available combos for the Ghost cam check here. For the stage 2 Turbo cam check here.

Something we haven't seen mentioned yet is what torque converter you're running. If you want to stick with the factory stall converter we would stick with the Ghost cam. Even then the Ghost cam really responds well to a 2500+ RPM converter. With the stage 2 Turbo cam, we recommend a minimum of a 2800 RPM stall converter.

We'll keep an eye on the thread. Let us know if we can be of any further assistance.

I'd do the 8706R1. Easy combo to drive on the street.

Ghost23

I think that's what I'm going with.

Ghost23

Great info! Thank you.

I plan on going with the stage 2 turbo cam. My thinking is it's going to sound great at idle. Have way more power from idle to top end than the engine that's in it now. I'm not at all worried about smooth driving. It's a muscle car, it's supposed to be mean!
