heads or nitrous
#12
I bet your Regal is faster than your Trans Am already.
The nitrous will gain you about 1 sec in the 1/4
The heads, with supporting mods, about half that much.
If it were my choice, I would not go with the nitrous until you have done all you can mechanically.

well I talked to a couple ppl and found out that If the heads allowed the same lift as the intnse stage 3 heads I can run the 1.8 rockers and a cam. The only question i would have is how much difference in idle sound would the s1x cam make. I want it to sound "stock"

Have you ran the car at the track yet? Generally at 3000 feet you will loose 0.4 seconds off the 1/4 mile compared to sea level in a boosted car (proven las weekend by 3 cars that all raced on an oregon track recently as well)
I dont know what the additonal elevation would do, I'm guessing 0.6 slower. therefore you would need a car that runs a 12.9 at sea level. Your going to need one heck of a cam, heads and possibly an IC to run consistantly that fast.

its pertty Tame, and if all else fails you can raise the idle a couple of RPM'* and then you really wont be able to tell its cammed

but seriously I am not going to say I will street race i just want to know I have it if the need arises. I am thinking a small cam like the s1x and the rockers and higher shift points would be the icing on the cake.
hans no i have not run it at bandi yet but I did back home and alot of things have changed since then so I will post results from the track at 2100 ft after the 22nd but as for up here I got to douglas too late for T&T so no telling
and as for you silverbullet yes she is faster but my gf calias is faster then a car with a disassembled motor lol

If bang for the buck is the thing Nitrous is the way to go. Not the way I would go but that’* not the question. You’d still see gains with heads but with rockers you’d only get 2/3 the benefit opposed to you being cammed.
I plan on buying some heads during the winter and hopefully seeing 12s next spring or summer. I personally would be scared to put Nitrous on my motor, it can be very dangerous if you are not careful with it.
My thoughts exactly Paul.
You would have a hard time maintaining the stock sound with the S1X it’* very streetable but much different then stock.
Here is a crappy video of my my motor with a S1X cam firing up & lots of backround noise

gtp with s1x sounds pretty good
the one thing I can't remember though is, is it duration that helps with the top end and the lift the low end torque?

LOL..
The sound of the S1X all depends on how you decide to run it. If I drop my idle down to where Ed'* is...mine will sound very cammed. The idle on the current tune is ~100 rpm higher than stock and 99% of people wouldn't have a clue that I'm not stock until I get into it.
If the heads have the clearance, yes you can add the 1.8 rockers along with it. Expect that it'll add to the sound though. Keeping the valves open that much and that long..you are going to hear it.
When talking heads and cam though..you are going to use a bunch of gaskets, oil, coolant etc etc. That will bring your costs up. NOS won't need those gaskets unless you mess up. I'm in no means a NOS person or have any real experience with it. A good chat with Curt Martin at SEBF last year changed my opinion on it. If done right..it'* good power and safe.
