OK guys it's been a while since I posted. I need some advice.

When I bought my car it had all the components I have listed below. What I would like to know is, how can I tell if I have a cam or not. I still have not been able to get in touch with the guy that had the car before me because he is still in IRAQ. I don't want to pull the car apart to find out. The car Idles rough but does not have any mis-firing and pulls strong up to about 130 then starts to slow a little. I have a new opti, water pump and O2's. The car has no headers or cats.

The reason I ask is, this morning, I took on a 92 formula T/A GTA with headers LT4 hot cam kit flow master catback CAI and all bolt ons and A4. We were side by up to I hit 4th then I pulled over a cars length on him and was still pulling at 125 when I started to back off.

He should have taken me since I am mostly stock. What do you all think?:

What else is done to your car again? I think you forgot your sig.

Anyway I would say you have a really strong running car. I'll bet you have some kind of mild cam in yours, or he doesnt have the mods he says.

 

Sorry but something must be wrong, When I vew the post I see the SIG. But here is what I have.

I'm surprised with 3.73s that he hung so well with you, I would have bet that you beat him by a little in the 1/4. The 3.73s really wake up an LT1.

 

You can try pull one of the valve covers off and taking a gander. If there's aftermarket springs and rockers on there he very well may have throwin a mild cam in there or just put 1.6 rockers on but it would give you at least a hint of whether or not it's been changed.

 

Also it seems almost everyone goes with Roller Rockers when installing a cam, you can just pull the passenger side breather or oil fill tube off the valve cover and see what's under there.
