Holley headers and mounts

[L92 OLDS]

Was there any modifications needed or did the headers fit without issue?

DIrect fit....No issues or mods required.

Guess I'm not as up to date as I thought. I didn't know they made a Gen III LS3. I thought all LS3's were Gen IV

All LS3 are GEN IV. The issue is these all are DBW but I am building it to be DBC so I cannot use the LS3 PCM. I will have to use a LS1 PCM and they do not support the GEN IV knock sensors.

Ummmmm, just use gen 3 knock sensors?

I will be. Which is why I asked about clearance since the Gen 3 sensors will stick out more than the Gen 4.

I'll get some pics with headers mounted. Give me an hour

There's a full 5" of space on the driver side and the headers are pulled back behind the passenger side bolt holes that you could use for knock sensors on the block. I think you will have lots of room. I can thread a knock sensor in if you wanna see for sure.

These are the 1 7/8" long tubes. So it ain't gonna get more crowded than that.

They're going to hit the crossmember.
