Stalling Vette, please help. I just installed a new 408, a new tranny, new DTE Rear-End, new stall, new suspension and a new fuel system. Car ran great for about 5 miles, now it stalls. I'm running open headers, the rear O2's are turned off. Could me being opened headers be the reason my car stalls after about 20 sec. of idleing, or as soon as you go to put it into gear..?
Hey put the exhaust back on see if the problem goes away.
I think the best way to get it right is to tune it with open headers. For some reason maybe the open header is not allowing the front 02 to get a correct reading depending on how close it`s to the end of the header.
I got one of those junk predator handheld programmers. The only thing the I found it good for is monitoring real time data fuel trims from the O2 sensors under normal conditions.

I pulled off the driver's side valve cover. Yes, well, I found our little problem... #7 cylinder rocker pedistol is broken. I can't believe it. I'll call Texas Speed on Wednesday. I'm sure Jason, and Jon will take care of me.. I'll let you guys know how it goes. The motor, heads rear-end and tranny only have 5 miles on it.

You have no idea. My only problem, is that these heads broke under idle. I am no where near breaking this thing in yet. I can imagine me being at the end of a 1/4 mile run @ 7000 RPMs on a 500 shot. I would probably have push rods hanging out of my *** right now...
It has to be the casting unless the intake port has been ported WAY to much .
Have the heads been ported by anyone ?
PS: Can you please explain how you are going to keep the heads on the car with a 500 shot ?

Good news, no, better then that, GREAT NEWS. I spoke with Jon fro Texas Speed. It seems there was an issue with a few sets of heade. "Casting #'s" There was a casting flaw. Fortunatly I am one of the last ones to have these heads. Since the issue came up, Texas Speed has replaced all of these heads with a newer biger and better head. This goes to show just how Texas Speed handles these kinds of issues.
As for the poss. damage in #7 cylinder, I am pulling the heads off right now. I'll keep you guys posted. My fingers, toes and hair are crossed hoping there is no or VERY LITTLE damage.... I have soo much invested in this project. I don't want to have to dish out another 5 or 10K to fix this issue. Texas Speed is helping with the heads, but I still have $300.00 head gaskets, plus my labor, and then I have to have these new heads drilled for 1/2" studs.....
As for how I'm planning on keeping the heads on the car with a 500 shot.. 1/2" studs, $300.00 O-Ring gaskets, a great direct port, a nice progressive controller and a great tune.... All of this adds up to my heads staying put..!!
