Hey guys...I am new to this board, and this is my first post. How y'all doin'? Just for the record, I did do a search, and read about two dozens old threads, but am still curious...
I have a 1990 GT, 180,000 miles and B-O-N-E stock. I got the car with the most hellish rod knock I have ever heard, so I started building a replacement. I'll give you a breif run-down before I move on to my question.
Wheeler Motorsports in Jacksonville is building my short block, a 331 with an Eagle Crank and Rods, Dished pistons, and a Canton main girdle. I already purchased a set of Edelbrock's Performer heads, and a Comp XE274HR cam kit.
That's when I started doing some research, and I guess this cam is pretty nasty for a SMOG'd car. I just wanted to see how many of you guys are running this cam and getting past California's emissions. I built this motor with around 8.8:1 compression. I will be ordering a Kenne-Bell Blow-zilla as soon as I get my tax return, but wanted to get the motor in the car, get the car smogged and registered, and get the motor broken in N/A first. Is this cam a bad choice (I bought it on Kenne Bell's reccommendation)? Would the XE266HR be better if emissions are a concern? How 'bout the E303?
Thanks in Advance,
Casey90GT

hello and welcome to the cafords
i have read on other sites about people having that cam profile or larger and passing smog, its just the tech that it depends upon if he will let you pass the visual(idle choppyness), good luck. any pictures of your car?

You don't want Edelbrock's Performer heads on a 331. You don't want a Kenne Bell on a 331. Look into AFR185 heads and a Novi, ATI or Vortech supercharger instead. Then don't go too crazy with the cam in fear of cracking the stock block with 500+ rwhp.

I have a 331 with a vortech and a XE274 cam. it passed smog. We don't do a dyno test in Redding just a snifer It has a nice lope to it at idle you will like it. good luck

The AFR 185's are the sh!t. But why not the Kenne Bell? I know the centrifugals can make more power, but I don't necessarily want more than 450rwhp. They should all be able to make that. Right? I know it sounds crazy with my power goals, but I am not building a drag racer. I just want a really quick street car.

Anyway...I am pretty sold on the kenne bell, but it's cam choice that concerns me.

So is 2Stangs the only guy that's running this cam and passing smog? I am hoping that somebody is passing a Dyno Smog with it. That 274 is smaller than an E cam's advertised duration, but advertised numbers don't mean anything. It has like 224 and 232 @ .050". That a lot bigger than the E cam's 220 and 220 @ .050". I want to make big power with that Kenne Bell, and that takes opening up the exhaust a bunch. I think the XE266HR will be choking my engine up. Any more advice? As far as cars failing because of a lopey idle, I am not concerned about that. I just want the emissions to be right where they should be for the lovely state of CA. Thanks!!! I appreciate everybody's input a lot.

we can't say it WILL pass, all we can say is that it CAN pass with everything working properly and a good tune

I just figured that more people were running it. Comp says it's their most popular 5.0 cam. I guess I'm being unrealistic, but I had hoped that like ten people would pop up and be like "I passed with it"...that's all. I appreciate everybodies help though. I guess I'll tell you soon enough if I pass with it.

no smog tech can fail u because of choppiness of the sound of the car.
and if all your smog equipment is there it should pass.ive seen nasty custom cams bigger then that pass with a good tune

It is a shame you are not willing to look at other types of blowers on a fox body. You only hear about strong running KB cars on '03 cobras but maybe your research shows something different.
I think I've read that 2Stangs is a smog tech which would explain why he passes smog with that cam ![[Big Grin]](biggrin.gif) Will passs, can pass and have passed are 3 different things. There are 1000 HP stangs around here that have passed smog Think outside the box.
You are correct about not being concerned about a lopey idle. Dyno smog is only reads smog levels at 15 and 25mph.

2stangs is not a smog tech, just an enthusiast that has 2 strong running mustangs. the dyno smog is actaully a little friendlier for larger cams compared to the idle test

I had the stage 1, I think the 274 will be better. In fact I have a stage 1 cam new in box for $100 if anybody wants it.

if your worried about cracking the block going over 500rwhp then why build a 331?...you could do over 500rwhp with just a 306 (even a 302) good heads cam and a blower...just trying to save you a couple of bucks...good luck...

Mr hungry Hippo I have had a CA smog liscence since 1983 and have done 1000 or so smogs OK. I currently work for UPS and we don't do smogs in house.So I don't do smogs technicaly anymore. I am also a ASE Master tech so please don't discredit me so easily thanks. BTW I didn't smog my own car and nothing special was done to it to pass the sniffer. So I am a enthousiest(how ever the hell you spelled it LOL) who has made a living working as a tech since 1985(I am getting damm old also LOL)

thanks...when I built my combo it had to pass smog that was as important as performance. technicaly it isn't legal since it is a stroker 331 and the cam isn't legal but it looks legal and will pass the snifer which is what counts ![[Wink]](wink.gif)

2 stangs, do you guys do the sniffer on a dyno, or just a two speed idle test? I have a buddy who is a smog tech, but I don't want to do anything to jeopardize the way he makes his living. Yeah, a stroker is illegal, and so is the cam, but smog techs can't check internals, and if all the equipment is hooked up, and the thing is emmiting the specified amounts of gasses, then nobody really cares. I don't care to have an offroad h pipe or a smog pump delete. They don't save that much weight, and they don't rob that much horsepower either.
In response to NO MANRZ, I have totally thought about running a Vortech and a Paxton, in fact I can get a better "Hook Up" on either of those brands than the KB blower. I think that a Vortech or Paxton or Pro-charger would probably make a faster ride, and definately lay down more power on a dyno. I just figured for a "Street" car the Kenne Bell/331 combo would be torquey as hell, and a whole lot of fun to drive. Not to mention completely different that what 90% of the guys are running these days. I really want to knock people's socks of with this car, and I don't just mean from stop light to stop light. I have a couple of things planned to really get folks to go ooohh, and ahhhh! I just want to know that my cam is a solid choice. Starting to sound like it might be.
By the way, for what it's worth, I watched an E cammed 347 car with 1.7's and a Vortech S-trim with the AMS pipe and PMS system smog with the lowest numbers I've ever seen a mustang put down yesterday. I guess it really is all about the tune. He also said he had over 100,000 miles on his stock H-pipe.

IMHO with 331 You are going to have plenty down low and a centrifical would match up top.If You are wanting a little more down low go with a T-trim? You are just going to be spinning the tires on the street, and unless You are running slick's at the track will probably spin em there also. What tires and what size are You planning on going with? Not trying to bash on You & I hope Your build goes well. Have You found someone with a similar combo to see if they like it?

I have been looking at the Halibrand Cobra III Deep-Lip rims. I don't know if I have a chance in hell of fitting a 17x9" front and a 17x10.5" rear, but that was my aim. I haven't found anybody with an engine combo like I am builing. I was thinking that would be the best part. And I won't be spinning the tires everywhere. I can pedal the throttle with the best of 'em.
