houston performance 292s regrind cams. I am sure someone is going to have something negative to say about regrinds but $450 for the cams and the sound amazing.

just did a quick search on alta vista...

When the intake valve opens and the piston starts its intake stroke, the air/fuel mixture in the intake runner starts to accelerate into the cylinder. By the time the piston reaches the bottom of its intake stroke, the air/fuel is moving at a pretty high speed. If we were to slam the intake valve shut, all of that air/fuel would come to a stop and not enter the cylinder. By leaving the intake valve open a little longer, the momentum of the fast-moving air/fuel continues to force air/fuel into the cylinder as the piston starts its compression stroke. So the faster the engine goes, the faster the air/fuel moves, and the longer we want the intake valve to stay open. We also want the valve to open wider at higher speeds -- this parameter, called valve lift, is governed by the cam lobe profile.

The animation below shows how a regular cam and a performance cam have different valve timing. Notice that the exhaust (red circle) and intake (blue circle) cycles overlap a lot more on the performance cam. Because of this, cars with this type of cam tend to run very roughly at idle.

Well yeah, it's obviously overlap causes the sound - but no one rating tels you this. Duration and LSA are just averages or averages of averages. Those two ratings just give you a glimpse of how the cam behaves. Go on youtube to figure out what you want, but I wouldn't go over stage II like V-8 is saying; getting cams for the sound in general I wouldn't advise, but at least stick to one that wont give you problems.

I only say do the monster cams if going high boost with extensive headwork and forged internals.

I don't think any of those cams work too well with boost, and the pistons would need to be fly-cut or have a huge dish for 2 of them. But lopey they are

Yes, they are $550 but you get $100 core charge back for your stockers. They are stock regrinds.

regrinds are pretty good, i have my powerheads stage 1 cams 270/270duration, 540/540 lift waiting to be put in, we just put the same set im my buddy's car, and they sound great, powerheads also has stage 2 cams with 285/285 duration, 540/540 lift

here are the stage 1's in a pretty much stock npi car, even with the npi intake

I generally don't like regrinds, but anyplace that pays you $100 for used NPI cams is okay in my book, lol. I wish i could just mail em mine and get a hundo

Since when do we buy cams by how they sound? You buy them by what will work best for your set up.

Yeah. Exhaust, tune, idle all dictate it. Vids of a car pre-tune don't help much. And a low idle can cause surging or dieing with cams.

They're all meant for boosted applications.

Yeah, i see the VT blower cams now, but crane stg 4's and XE278AH's are both N/A cams i believe.
