are there any smog legal cams for 99-04 gt?

[ADRENLN]

i was originally not going to do cams, because i wanted to remain emissions legal, but i feel that im not going to get the power i want just from p&p heads alone. i really dont want to compramise the passing sniffer.

what should i do? also this is a street car, but i want it to be fast.

future plans are the p51 and paxton novi 2000.

what stage heads would you think fit my application? was going to go stang 2 with a stage 1 cam to see if i could get by emissions. what do you guys think, im confusing myself now.

there arent any that are CARB EOd. however the less overlap generally the mroe emissions friendly.

The only cams I know of that are emissions legal is stock. But then again I would guess porting and polishing the heads may be against emissions as welll.

 

[bdcardinal]

actually porting and polishing isnt. in CA you are allowed to port and polish stock parts.

I have heard of people passing emisions with the vt stage I and II cams I think. I would think the tune you run would be the biggest factor.

I mean they are not going to fail the visual and the odbII test.

the only way you would fail is if the car litterly failed emisions. I would be 90% postive that stage I cams could be tuned to pass emisions.

yea i was thinking if i upgraded the cams, it would be with stage 1 cams....only thing is i was going to go fox lake and they use comp cams. i dont think i like comp as much as vt cams.

maybe ill just stick to the original plan and just get p&p heads with the pi cams, and see if i can get some kind of gain out of them. some peopl say with just heads i should see 15rwhp. i dont know though if i do this what stage should i go with, i was going to do stage 2 because the car will get a blower in future, but i dont want my lowend suffering a lot. would there be a noticable difference in low end loss between stage1 and 2?

Well vt will work with fox lake heads. same head. I can say if I was swaping cams and already doing the labor I would put in cams. you will have the nice springs and everthing might as well take advantage of them.

If you think you 90% positive on the supercharger make sure you get blower cams.

If I was boosting I would stick with a "stage I" (i hate that term). Basically run a bit milder cam so you have better road manners. with the boost you will make all the power you need. I mean n/a you run a more radical cam to build more power. with a stock shortblock you can make all the power you really want it to see without cams.

I have to say though with the price of heads and cams why don't you just run a more expensive supercharger?

I was going to do what you are doing and then I just decied to run the kene belle 6psi kit. tons of low end power. If you even want more just add the intercooler.

I would think that the 6psi kit, built rear and some launches would get some respectable times.

just food for thought I originally wanted to stay n/a until I talled up the price tag. I like the kene bell kit because you don't need the $1299 p-51 intake.

well i was thinking of just going to the blower as well and skiping the rest, but i would wind up building the engine first anyway. i wanted to replace my heads anyway, i think i have defective heads, im out of warrenty, so i figure just get p&p ones.

like i said i didnt want to do cams, i feel there will just be more problems with them, with tune and everything. however i am starting to think maybe the weakest cam would be ok. i dont know what move to make.

the reason im concerned is that from this point on the choices i make will effect the future mods as well, so im trying to work out some things before i make a choice.
