Was up to see Nick Agostino and this is what he came up with:

ARE StageI heads
Lunati Cam 218/224/114 554/560 Lift
Comp Cams Moly Pushrods
Comp Cams Lash Caps
Grot headers, if available otherwise SLP
ARE oil pump
Possibly LS6 intake
Custom tuning might be needed
He would do the install.

Car is '99 Z28, M6, 13K miles, with 4.10's, SLP ram air hood, SLP cold air, lid/K&N, B&B exhaust/Zed coutout, and 4.10 gears. Air conditioning is removed. It's not a daily driver. Mostly it's for having fun on the roadcourse, but I do want it streetable. Would appreciate any comments, keeping in mind that I'm cam ignorant.

 

From what I have read and studied, around 400rwhp

With that setup, I would definitely upgrade your rearend. Something in the neighborhood of 400 RWHP with an M6 hitting 4.10s on a stock rearend = asking to leave parts in the road.

Not the cheapest thing to do, but definitely cheaper than the alternative.

 

ARE StageI heads...good bang for the buck.
Lunati Cam 218/224/114 554/560 Lift...why this cam? Are going to be spraying nitrous? Is that why your going with a 114 l/s on a M6 car?
Comp Cams Moly Pushrods
Comp Cams Lash Caps
Grot headers, if available otherwise SLP...headers will really wake up a heads/cam car.
ARE oil pump...always good insurance.
Possibly LS6 intake...two words, DO IT.
Custom tuning might be needed....might..but probably not if your play with the TB. (since your and M6)

You dont mention what springs you are going with? 918's?

Good luck. (I'm still curious as to why THAT cam....espcially since it is NOT a daily driver.)

Springs - Shown on the proposal sheet are High Perf. Valve Springs, also Viton Valve Seals, Machined Locks and Titanium Retainers, Set all valve spring pressures and heights. Valves = Stainless Rev 2.02/1.57 valves.

As to the cam - Like I said, I'm cam ignorant and this is the main reason for the post. Re your curiosity about the cam, are you thinking it's not Aggressive enough?

Actually, I thought this setup would be overkill for my purposes. My car dynoed at 319 f/p at 4600 and then starts to fall off. What I want to accomplish is to raise torque somewhat starting at the low end and extend the max out to about 5500 if possible. Maybe headers and the right cam would do it which is what I had originally thought of. And like WeatherGuy said about the rear end, I thought of regearing to 3.73's. I just want to do this right so not a lot of trouble later. Thanks everyone.

 

Go with 11:1 compression and try a 226/226 cam on 112LSA <img src="gr_grin.gif" border="0">
That would be a powerful performer <img src="gr_stretch.gif" border="0">

Raughammer,

Re the springs. This was discussed with Nick, and I assume he had made the selection correctly. I definitely want springs that will hold up.

As to maximizing torque in the rpm range being used. Sorry if my wording was misleading. If possible, I would like to attain max torque at around 5500 rpm if possible before it begins to drop off, with some increase above it's current max of 219. Lowest rpm I'm concerned with is about 3500.

Truth be known, I don't need or want 400 hp. My car dynoed at 302 hp and if I pick up an additional 40 that's fine with me.

If the above is possible, my first consideration is whether it can be done with just cam, headers, and tuning.

I realize that for the roadcourse I probably should regear with 3.73's regardless.

I printed out all 35 pages of your cam info. Hopefully I'll be a little less cam ignorant after studying it. You're owed a lot of thanks for taking time to put it up here.

 

I don't think you want to make peak torque at 5500 rpms. That would be the peak torque for a motor that probably is shifted at 7500-8000 rpms right? <img src="gr_stretch.gif" border="0">

Again, maybe a problem with wording. My car makes max torgue at about 4600 then begins to fall off. What I'm trying to get to is whether the torque curve can be leveled off somewhat so as not to drop off so fast. I'd like to have the car pull harder in fifth gear on the roadcourse. But as I said before, maybe my gearing is wrong. With 3.73's instead of my 4.10's, it could be that with the engine turning slower, I could stay in fourth at times and not run out of torque as apparently happens on the straights. Hope I'm not going off on some crazy tangent here.

 

Nick is using double springs in all of his packages AFAIK.
He will definitely match the springs to the cam and the head porting to the cam as well. I would go with grotts or hooker long tubes and not touch the SLP's.
Good luck, should be a strong runner!

I got my stage II's a couple months ago, and they came with K-Motion K-800 dual springs. Good to .700 lift.

Yikes!!! Are you using them? Are they working?

The K-motion K-800s *flattened* my lifters.

Just a FYI.

All the rest of the above info looks good. I would DEFINTELY do the LS6 intake. No negatives, 15hp for 500$. You wont get that kind of deal after this. I would do something really close to 221/221 on a 112. You could do 114ls with little degredation. I would suggest 114 if you are in a pollution unfriendly state, or you dont like to have a car that rumbles and shimmies a little. The 112 will *slightly* help you on corner exits, if the 4.10s havent gotten you there already.

Yep, I'm using them and haven't had a problem yet. I have to assume Nick knows what he's doing <img src="gr_stretch.gif" border="0"> He had problems with whatever brand he was using before, so he switched.

I don't have a real big cam either though: 218/224 .528/.535 114

I am sorry, but that explanation does nothing for me as far as info goes. "High Perf. Valve Springs"
There is no info there... BEFORE you buy you really should know wat spring pressures that cam (or the one you decide on) requires and if the springs you will be getting will not only cover the required pressures, BUT will offer you enough "safety net" room so that you will not be changing them out next year. One caveat; Tooo much spring pressure can also be a problem.

In a word NO. And this is coming from a member of the "smaller is better" cam club.

Most cams will not raise torque from idle to 5500 over a stock cam. They will have to trade the torque gained up top for torque lost down low. I am not saying it cant happen. But that is a BROAD power band your describing. 800 to 5500 (torque wise) You will be around what RPM most when your racing? You should look to maximize your torque/HP in THAT RPM band.

My cam page has a lot of input from fellas who have used THAT cam and many others. Maybe one of the entries would help point you in the right direction.
