Not to throw fuel on the fire, but emissions aside, both cams (306 or 847) will work great. They are both tried and true grinds with repeatable results on given applications. To say a comparible custom cam will make huge improvements over either of these is a stretch at best. Set up the engine and valve train correctly, pay attention to every detail, and pay to have a quality dyno tune done (not just at wot), and you'll get good results.

You will definitely not mistake this cam for stock, unless you had the cam ground with an LSA of around 115-116 degrees, or you increase the idle speed.

From what I have read, if you were really looking for "tamer sounding" (sleeper) cams.....do a search for the "Cadillac Cam", SpeedInc makes it. Crane and LPE also make a couple of stockish sounding cams that make good power.

Edit: I see you've already looked into the "Cadillac Cam".

 

Well I have mixed feeling about emissions. I have "friends" but one of them could lose his job or quit at anytime without giving a damn if I have an inspection sticker. I have Crane 10308 springs so I wanna stay within the limits of them. I'm considering the CC306 because of the power band.... I just like it. The GM847 is the sickest sounding cam. If I decide to stay tamer with it .... I'm going to sell the CC502 and get a 503 or 306. I have a little time to make up my mind.

 

I'd love to see it done.

Since you have OBDII you don't have to pass a sniffer test. Just fab up a cat/converter Y-pipe if you're worried about visual inspection. As long as your PCM is tuned accordingly you should be golden. You are allowed so many "not ready" tests when doing emissions. Your friend should be able to tell you or you can study up on it if this is really worth it.

 

Ya I thought about going with cats but long tubes don't leave much room for them. I may just say screw it and let my friend "pass" it.

 

Not going to use the CC502?

 

In a quest for more power... I may not.

 

Have a dual cat Y-pipe made for such an occasion. I have two. One ORY and a dual cat Y-pipe. As long as it's done correctly it'll be fine. My car is lowered and I have no issues with it scraping. In fact, I had a guy in Plano fab it up for me. Here's his info:
Nick's Mufflers
Address:
6340 W. Plano Pkwy.
Plano, Tx 75093
Not sure if he's still in business. He's costly, but does very good work.

 

Ya these Eibachs are what really make me not want to go too crazy with the exhaust. I was contemplating a true dual setup if I just go with a friend at the inspection station.

 

Won't you still fail visual with LTs?

 

Ya but most places have "Bubba" working the tools and all he cares about is the read out. I went to a place in Arlington where the guy inspecting my car looked EXACTLY like Osama Bin Laden. Even had the head dress on. He didn't do anything to my car except drive it up on the rollers, plug it in, and put the sticker on. Didn't check anything else. My tires were shot, no cats, high beams wouldn't turn on, and I know there had to be something else it would have failed for. haha

 

makes me (almost) glad I live in Oklahoma where we have no such tests.

 

I'd have hung myself long ago. OK ftl. TX ftw.

 

Man I told ya...find me a good IT job down there and I'm on my way

 

What kind of IT work?
