Need help for sleeper build! So i have a stock 02 z28. I wanna put on ported ls6 heads, converter, 373 gears, and a cam. The thing is its gonna be a sleeper. I wanna know if anyone else is running a cam with stock exhaust and manifolds. And what would be the best sleeper cam. I was thinking just throughing a zo6 cam in it.
I'd do something like 217/232 .605/.575 117+3 LSA... you can use the LSL/XE lobes for it. That's similar to what Thunder used to use in their Cheatr cams that used stock manifolds.
One other thing you could do is run LS7 manifolds, and then put a hidden nitrous setup on there... that'd be a sleeper.

I first got into the LS game in 2003 when a buddy of mine put ET streets, 3.73 gears and a 150 shot on a bone stock 99 z28 a4 and ran 11.20. That thing surprised a lot of people. Just food for thought if you want a sleeper. You can hide a wet kit very easily.

Ok, I am SURE I'm going to get flamed for this....(I am somewhat old school).......A reverse split cam theory is they make up for poor intake capacity and exhaust expulsion. I had one of the old TR230/224 and it made crazy low end torque (which IMHO is what is needed for "street play").
OK guys, let the flaming begin

For ultimate sleeper factor you want a short intake duration cam with biiiig lift and a long exhaust duration with low lift plus wide LSA with lots of advance ground in.
So how about 218/230 ish, .600 and 115+4 ??
Oh and it will idle like stock with -4* of overlap and a tune. Most people would be very hard pressed to even know that he has a cam in there from listening to his exhaust.

^^Agreed. Also the money maker kits are almost impossible to find. So can someone help me out with a link. And im actually gonna do what jake said and put on some ls7 manifolds. Im putting this sleeper together to get money to start building my lsx twin turbo that will go into it later in life. Once everyone realizes my car isnt stock😃
The cam I posted will make plenty of torque and carry the power, even with stock manifolds. I still think the LS7 manifolds are a nice upgrade. Worth probably 10-15rwhp.
Add a 150 shot to it, a decent converter... maybe SS3200 or SS3600 and the 3.73s, drag radials... you'd have a very fast car that sounds bone stock.
Talk to Nitrous Outlet about their money maker kit.
I would go to either Tick or BTR and get a custom ground cam similar to what I posted. Add the BTR Trunion upgrade, Ported Oil Pump, Hardened Pushrods, Katech C5R Timing Chain, BTR valve springs, and the gaskets.

Then I demodded it and traded it in on a truck.
Not a killer car but definitely ran strong for being in the 2003-2004 era.
My License plate even read SLEPRZ. It's on my dually now. LOL

And even if they did fit, won't exactly be "sleeper" as most people will easily be able to tell those aren't stock.

thats a good question. Idk if the ls7 manifolds would fit in the fbody. But if someone would complain about the 10 extra horsepower. Im going to laugh at them. Still would have full exhaust. Plus i could talk my way outta that anyways.
