We built a 427 LSX 2008 RC silverado (cheyenne down here)..

D1 pushing 12 pounds...

The thing is that after a hard wot, not even a full track pass, just a hard wot on the street, we open the hood and the headers are flaming red...

Is this "normal" or should we look into other brand/type/or material for the headers?

Thanks for any input..

edit: headers are edelbrock

what kind of headers do you have now? coated or not?

just edited the post... headers are edelbrock not coated.. (grey color)

Are those stainless??? If not then I would try to wrap them to see if that helps... I personally would go with some QTP or something equivalent... How hard are you pushing that blower?? I'm thinking of going with a LSX block 427 but was wondering if I'd even be able to strap the D1 onto it...

Several things cause headers to glow. Way too rich, way too lean, timing too retarded, shitty headers. Take your pick.
Headers should be coated at least. If they're not, get em coated inside and out. That alone may take care of it.

Doublecheck the timing. If it's seriously retarded, the headers will glow due to the final combustion taking place in the headers instead of the chamber where it belongs. Worst case it will burn through your headers. Remember that the timing can be retarded via the knock sensor and knock retard, so check that too.

how about a very restrictive exhaust, but i would put my money on thin walled uncoated headers being the problem

Lets see some pics to see how thin or thick the material is-

you need to get that car professionally tuned before you end up buying another shortblock

Haha, that just doesnt sound very politically correct

The guy that tunes our cars has HPT and a LM1.. i have not talked to him yet.

Im going to check the exact model of the headers, do some research on them and have a chat with the tuner..

Is it lean because I have heard that a lean condition can make your headers get really hot.

Definitley get that thing tuned, that doesn't sound good at all. Even if they are shitty headers

Sorry, should have said "Glowing like a ******* Mongoloid"!

Headers were 1 3/4... never noticed that when installing (such a rush to finish it)..

We are switching to custom 2".. they started today.. lets see what hapens.. just saw some AF logs and truck is not lean.. if any, it is still a bit rich.. timing is low, but not that low..

im wagering they are too thin.... try coating inside and out
on a set we had to coat inside and out as well as wrap to keep heat down

LC

We got a custom 2" haders made and that solved the problem, truck is running fine, we will be trying a F1 by the end of the year

thats what I was going to say, 427 plus blower = bigger headers.
