stay with stock cam, or go to E303 (must be emission legal)

Xeryus -> stay with stock cam, or go to E303 (must be emission legal) (5/7/2008 4:46:16 PM)
Hello folks, I need some help making this decision. I'm in the middle of buying all my parts for my engine build up. Below is what I've got/am planning on. The question is, should I stay with my stock cam or get the E303. The reason I'm looking at these 2 is b/c of emissions legality. This car will be my daily driver and there is emissions testing here in BC. Also, since I'm planning on going turbo eventually, I don't want to spend the time and effort to get a custom ground cam when it is only going to be temporary. (Not to mention, I'd be screwed if a custom ground cam didn't end up passing emissions) Parts list: 347 stroker kit AFR185 heads (w/ 1.6 roller rockers) Holley Systemax II intake manifold (upper & lower) I really can't decide. On one hand, I can stay with the stock cam and not have to worry about it, plus its a bit of extra cash in my pocket. But on the other hand, since the engine will be totally apart, might as well throw in a new cam and get some extra ponies...

either way its going to hold you back A LOT....i have the E303 and its decent....not great but sounds nice,

I would look into a comp cam, or even a steeda cam. I have had 2 E303s and 1 F cam, and i didnt really care for them that well. They did sound good but for power they wasn't that good.

Yeah, I know they'll hold me back. I'm really choked about that, but it's only temporary. A good sound is a bonus tho. Gotta sound good when sitting at a red light, ehh? [:)]

94GTPRO5.0 -> RE: stay with stock cam, or go to E303 (must be emission legal) (5/7/2008 5:06:35 PM)
yes they have to sound good sittin at red light, and with a E cam they do sound good, really good HAHAHA

or you can get some 1.7 rollers to increase slightly and remain emmisions legal

You could have a real custom cam designed for a turbo setup + be emissions compliant now, and then install the turbo. Keep in mind that the E303 is a cam (as the other alphabet cams) designed for a 302, it will respond and work totally different in a 347 setup. Why go through the cam install + PR length & geometry check, etc, etc twice for your engine?

Okay, then say I were to call a cam company and ask to get a custom-ground turbo / emissions legal cam. What technical info would they need about my engine to be able to make the cam?

But you're totally right, the stock cam wouldn't get anywhere close to what the engine could do. Maybe I should just get an N/A-grind cam for now...

When you're ready, you fill-in a build sheet with all the information regarding your combo, and send it in. Over the phone camshaft "designs" are questionable.

The stock cam wont give you the full potential of your heads. Small heart and big lungs is not great anotomy.

Xeryus -> RE: stay with stock cam, or go to E303 (must be emission legal) (5/9/2008 12:38:18 AM)
Okay, how about this; 1) N/A cam for now, turbo cam for later. More money overall, but more fun too. 2) turbo cam now, and just wait for the turbo to come in. Less money, but not full potential at first. stanks347, nice setup, according to your sig. what does she run? street tires?
