Hot Cam!

[smike07]

Whose going to replace their stock cam for the GMPP hot cam? It's a painful job, but I know I'm game! That's one sweet way to get the Camaro up to 472 ponies! It'll cost about $500.00 but it's relatively cheap considering many other alternatives. After that I'll add an intake. I may tack on a set of Kooks headers and an X pipe, and Corsa mufflers. They're expected to add an additional 30 horses. I don't want anything to look obvious when I open the hood, so I may just drop in a high flow filter into the stock box. It may only add 6 horsed or so, but it still equates to a 508 horsepower engine without a blower. I won't add one of those until she's paid for.

Thats actually a really good idea i plan on doing something similar. If i find a new cam for $500 at the time i will def opt for that but i wont settle for the new camaro without a blower. I've had my heart set on a supercharged V8 (nothing like that whining sound to accompany the high revs) since i first heard about this car. How come you dont want it to look obvious you had work done when you open the hood? Haha you have to be one of the only people I've ever heard say that.

I will prob be doing the same thing as you guys but yeah i want ppl to be afraid when i open the hood

Installing a Hot Cam would be on the top of my list for Mods, but I live in MA and we have strict Emissions testing. I've done a little searching regarding Corvettes with Hot Cams passing emissions testing but haven't found much.
Does anyone here have an experience with Hot Cam swaps and Emissions testing?
Thanks

If it doesn't void the warranty then I'll definitely install a hot cam if not for the performance boost than the awesome lopey sound once you couple it with a custom exhaust.

Because when I stomp the Mustang GT500 and Challenger SRT8 on the track, I want them to wonder why the Camaro that only has an exhaust system and a heavy-footed driver just left them in the dust! No, not really, I'd tell 'em.-- I personally like things to be left the way they are. I suppose later on down the line, shortly before adding the blower, I'll bore the throttle body, and possibly send the heads, lower, and upper intake to be ported and polished. That'll be after the warranty is void. She'll still look stock, but she sure as hell wont run like it. That'll be a minimum of 550 horses and counting. Toss on a blower and she'll likely do what the ZR1 does... only a butt-load heavier. Carbon fiber can only go so far without cutting her all up. The bumpers, fenders and hood will certainly be replaced. Good God this is getting expensive!

I'm planning to do the same mods as you exept for different brands. Once it's out of warranty, bring on the procharger and plates that read " KR THIS".

The original Chevrolet small-block inspired enthusiasts at all
levels, and rapidly became the preferred engine of serious
builders. The basic architecture was so well-thought-out, that
other than a few tweaks, very little needed to be improved.
Displacement and power numbers continued to rise as bigger
bore sizes were offered, and head, piston and intake technology
improved, leading to gains in durability and performance. But,
the basic engine remained: an iron block, iron-head, pushrod
driven, naturally aspirated model of efficiency.
The bore potential of the small-block was aided by two innovations—
green sand casting (a Pontiac process) and Siamese cylinder
walls, which eliminated coolant channels between the block’s
cylinders; both advances allowed for more “cutting.”
These two agents helped push the small-block dimensions from
the original 265-cubic-inches to 283, 302, 327 and eventually 400.
But, if size is one measure of performance, weight is another, and
ultimately GM engineers knew that to keep the Chevy small-block
on the leading edge, a serious re-design was in order.
While the Gen II engines were little more than a face lift (reverse
cooling flow). The Gen III and IV engines of the LS series were
a radical departure. Iron blocks were replaced by weight-saving
aluminum blocks with cast-in iron sleeves. Recognizing the
monumental torque and horsepower ratings these engines would
see, the block was designed with six-bolt main bearing caps.
Improved intake technology and hotter camshafts also greeted the
buying public.
The Gen IV series also brought in variable valve timing and displacement
on demand technology that allowed the user to shut down
half the cylinders for fuel savings when the power was not needed.
The LS series now has culminated in the introduction of the
LSX block, a marvel of engine technology co-designed by GM Performance
Parts and NHRA legend Warren Johnson. The iron block can
be bored and stroked to big-block dimensions at 454 cubes.
Today, as has been the case since 1955, the sky is the limit for
enthusiasts at all levels, with crate engines and components
available to take a builder anywhere they might want to go!
