Cam w/ stock manifolds? was just wondering if it would work ok to have an aftermarket cam (.570-.585 lift range) and STOCK headers? the ONLY reason im not getting longtubes is b/c i have a legal situation and can't get in trouble for a loud car. so will it work, obviously i wont see the same gain, but could it work ok and see 20hp or so or would that mess a lot of stuff up? Thanks

get some mufflers to lower the volume. You'll be leaving a LOT on the table without longtubes. Maybe run some true duals with bullets before axle..and mufflers after the axle.

If your only reason for not wanting headers is noise:
Put longtubes on the car, catted y-pipe and a bullet style muffler (bullet, sweet thunder, spiral flow, borla xr1 etc) in the i-pipe before going over the axle into your current catback (which is what, btw?). That'll be plenty quiet and flow great.
Adding pretty much any cam other than the cheaTR cam is going to pump the motor full of air that the stock manifolds just can't get out quick enough and you'll be choking the motor.

What about the tr244/244 cam? Anyone? Its smog legal in cali so I've read. Im in the same situation just wont have the money for long tubes at the time. Sorry not trying to hijack thread. If not I guess I'll look into the cheater. Whats the power difference between cheater and tr244?

LT's are important, not for flow. But for scavenging, this is where most of the extra power comes from. Mids, shorties and stock manifolds do not scavenge, either at all, or not sufficently in the rpm range of an Ls1.
If your in CA then your **** out of luck as CARB approved shorties are the only legal choice.
Everyone else should ALWAYS opt for Lt's on a n/a setup.
If you really plan on sticking with stock manifolds then Thunder Racings Cheater cam is designed to work well with them. However it would still perform better with Lt's. GM's Hot cam may be a cheaper alternative.
There's no reason you can't have Lt's and a good flowing exhaust and still be as quiet as stock. It's all about muffling?
Lt's with catted Y should not really be any louder than stock manifolds and cats using the same catback. You can always add in extra bullet style mufflers, these won't affect performance or flow, but will reduce db levels.

"You can run any cam you want with any manifolds you want. Even the bonkers T-Rex cam could be used with stock headers. However you just won't get the full potential."
so if i decide to get say a Magic Stick 3 (237/242 .603/602 112LS) that with tuning it would work just fine, and the only thing that would happen is that instead of the 55+ rwhp i should get from the cam i would only get say 35. ???
i just want to know if something harmful will or could happen to my car if i do that
Thanks

i realize that but my question was simply will it work w/o harming or potential harming my car as long as i have a proper tune? because long tubes may come later, but for now I cant afford to take a chance of getting in trouble with the law. so i dont really want throw a CheaTR in there now and then end up gettin long tubes and switchin out to the cam i really want....
