Ls1 engine noise after swap Excuse my ignorance as this is my first v8 car.
I have a mail in tuned ls1 in my e30, it's a ls from an 02 Camaro with 243 heads, sns stage 3 cam, springs/retainers and pushrods.
The car was mail in tuned but still idles horribly. It can barely stay on and it sounds like it's dying (and actually dies...)
I posted a video below, is the engine supposed to be so loud, or did I get the wrong pushrods? it sounds like I have a massive vaccum leak, but everything is capped or pcv connected.
Could it be the intake gaskets? I did not change them when I swapped heads.. (dumb mistake).
I really can't tell if it's supposed to sounds like this or if it's running very wrong.
I drove the car around and it's insane, but it's a 2500 lbs car and I have nothing to compare it too.
Thanks for the advice from anyone

I kinda expected to have the car tuned after the install, but I'm just a little worried on driving it.
I'm used to the straight 6, which was fairly smooth. But this thing sounds like a sawzall, and doesn't want to idle whatsoever.. I know the cam is aggressive,but I think something else might be wrong.

I would either have someone with experience come look at it or have it towed to them.
I can't tell anything from the video. That's a pretty aggressive cam so without a good tune it will idle really ruff. Here is another video on youtube you might be able to compare it to. Air far as the huge vacuum leak you are hearing, Are you sure it's not just the sound of air being pulled into your open air filter?
