Im curious if any of you guys have ran a TR220-112 and had any problems with smog, especially in CA. I know TR says go with a 114 to be on the safe side, but with a good tune is it passable? I don't want to have to swap cams to pass smog, but I would like it a little lopey at idle. Thanks in advance I'm ready to order, but undecided. Mods if this belongs in western feel free to move

 

at least you have until 09 to have to worry about it.

 

i'm running the TR220 112lsa and dont' have any problems...it sounds killer

 

I have the same concern as you. I just recently installed a 206,210/.510,.510 at 112 LSA on my 99 5.2 dakota. I was told by a very reliable source that as long as i have a fresh tune up, get a near 200 degree engine temp, it'll be near max on the emissions. I have until 09 to worry. However, I'm going to get a "test only" next week to see if all is well. Good luck on your cam pick.

 

224/224 112s pass all day long with mediocre tunes, a 220 112 should pass untuned

 

news to my ears. I've heard of 224/224 on 114 lsa cams passing but I know of at least 2 with 224/224 on 112 lsa that didn't pass.
