1st start up after heads/cam swap?
Hey guys-
I just have a quick question as to what to expect after the first start after a heads/cam swap with no tuning?
I fired the TA up today and she started with ZERO problems and idled like a champ for about 5 minutes..
I then shut it off to finish up a few small things I had to do on the car.. Then we started it up again and just eased it down the road and back and it's "running" but it doesn't really run very well at all..
Now, I am thinking this is to be expected, as it has ZERO tune on it and I was running open headers..
Just wanted to make sure this was typical..
Thanks
Jeff

Definitely needs a tune, my car did not want to idle at all after the first head/cam swap. I threw an idle tune on the car with HPTuners and then it ran OK until I could get it to the shop...Now my tuner is coming to my house when the 408 is installed to get it going. Then I can break in the motor, rear, and trans and get a dyno tune. John02SS from a local shop is hooking me up.

Yeh, I'm gonna get a Wait4me tune and then get a local guy to come and setup it up better if it needs it..
My schedule and the tuners schedules just don't mesh yet..

Hmm.. This is making me a lil' worried..
My car didn't just not want to idle but it didn't seem to run "right."
I drove it down the road and under power it just didn't feel like it was happy.. After I had driven it for maybe 3-4 minutes, it started running pretty rough...
I was attributing this to the heads/cam install.. ??? Is this normal?
When it is cold, it is idling "ok" and seems to rev ok..
Maybe the tune will clean it up..
I threw quite a bit at it all at once..
Ported TB
LS6 Intake
PowerBond UD Pulley
TR224 112LSA Cam
Texas Speed PRC Stage 2.5 5.3L heads
I sure hope it's not jacked...

Yeh, I guess I need to recheck all the connections... It was smoking a little bit...
At one point, it kinda felt like it wasn't running on all the cylinders... Felt pretty rough...
Those of you who are talking about it being driveable, was this after both a heads and a cam swap or just the cam swap?

I am going to get it dyno tuned ASAP.. It will be mid-January.. My tuner is out of the country and won't be back until Dec 23.. I have sent my PCM out just to get it up and running...
