Biggest Smog Cam With Stock Cats

Great thread: Just to give more input on the CA situation... One problem I have run into is that they are getting really fussy about the visual inspection - checking things like long tubes, legal CATS. I used to be able to find someone who would pass it for about $200, they have all (the ones that I used anyway) been shut down (our tax dollars at work). I am sick of the whole business. I was running a 220/220 on a 112 with long tubes with SLP 3" cats and was tagged as a gross polluter. At present I am putting a 2004 LS6 cam, JBA shorties and fabricating a custom 3" exhaust system. I am using CA legal Magnaflow cats (2.5"). We'll see how it goes. The HS 1.8 rockers provide approx. .580 - .590 lift and I'm hoping passing SMOG becomes routine. I mostly AutoX the car, so I don't need HP, I need torque. I'll let you know how it turns out. Good luck to us both.

True..but he wants to use shorty headers for smog, and a single pattern cam like the 220/220 would be a poor choice. You need a cam thats exhaust biased for a shorty/stock manifold setup. The cheaTR cam or the EPS one thats designed for a restrictive exhuast would be the way to go IMO.

If I don't sell my car, this is the cam I will probably be using. This would be great for stock manifolds/shorties, and sounds like its easier on the valvetrain than the cheaTR v.3.

That looks pretty interesting.
EPS reccommends dual springs.
You could also go with something like the PAC 1518s, unless you have good springs allready.

cuz i was just curious. after reading this thread it has made me think a lil bit about my setup. i most likely was gonna go with a cam that would work with my exhaust manifolds. but after reading this i am thinking about just going with a normal cam.
did u just put on the stock exhaust parts with your 224 cam and drive into the smog station and it passed? or did u need to have it tuned with your stock exhaust parts to have it pass?

With this EPS Cam I wonder if the profile is comparible to Comp's XFI or XE lobes.
Some cams even use dual profiles which will require different length intake and exhaust pushrods.

i literally just drove home from the smog shop and my TR224 114LSA passed with EASE with stock manifolds, cats, etc.! I also have a 3800 stall and ported and polished LS6 59CC heads. My buddy passed smog with a bullet cam 222/226 .595"/.585" although I forget the LSA. Here are my results for those who are interested-
15mph- c02 13.9%/ O2 0.7%/ HC 14PPM/ CO .17%/ NO 162PPM
25mph- c02 14.0%/ O2 0.6%/ HC 10PPM/ CO .18%/ NO 147PPM
now of course this was with a good driveability tune, but as you can see if was no where close to failing!

You passed with flying colors. Very encouraging.

update, i have run a best of 11.9@111 with a few suspension tweaks and a one legged 10 bolt. rear end is getting rebuilt now with 3.73s and a couple more suspensions tweaks. hoping to see a couple tenths improvements.
