I have two questions below - but a little inside info before you answer...

I am swapping '01 LS1/T56 into my '68 Chevy stepside C-10 truck. I had been told by some people the stock WS6 headers wouldn't fit, but I found the manifold and cat slip right in, no problem! More info on that:

Anyway, long story short here is my problem. See the little flange that sticks out of the heat shield on the passenger side manifold?

Well, I need to grind it down to clear the engine mount and frame, but I have tow questions:

1) What the heck is it for? Looks like it was designed to be tapped for something?

2) IS it safe to grind, and if yes, how much can be safely ground down? I'm assuming it's hollow on the other side.

Thanks!

I have some 98 manifolds that I just pulled off (camaro). They don't have that tab. I've heard that they're a bit more restrictive, but I don't know for sure. I'll post a pic if ya like? I'd sell them for cheap!!! if you want 'em!

Just looked on my car, (02 camaro) and it dosent look like anything goes to them. The tab is just there, lol.

Not sure about that. I haven't noticed those on my '01, but I haven't looked real closely either. About being told they wouldn't fit, I was told the same thing about using the manifolds in my '69, so I dished out $500 for S&P headers, then I find out later that the factory manifolds would have fit

Anyone know how far down I can safely grind that thing? I am amazed how cleanly and nicely these fit into my truck. Plan on posting a huge "HowTo" thread once this is all done. Any advice anyone gives RE: header modifications is going into it for the entire community to benefit from.

Glad to hear I'm not the only one that had this problem

I say be a pioneer and hit it with the grinder!

I've got my Dewalt 4½" ready to go at it. I'll give it another hour or two before hacking away

Hell, if I can get the hydraulics in today, all I'll really have left is figuring out the gas pedal setup

Ok, the '01-'02 is a no-go on the passenger side. In addition to that little jut-out being in the way, I notice the flange is rubbing the frame as well when bolted all the way down. I'm just gonna contact ashape about his I guess. Hopefully I'm not aimlessly dropping cash on something that doesn't work.

Not sure what the heat shield on the outside of this guy is good for :\

Anyways, some pics for reference - will be removed eventually, so if this is of interest you, right click and "save as"
