GN Engine into 87 IROC ?'s
Now, I know a few people on the board have done the swap like fly89gta, my questions are: What problems might I run into as far as getting the parts for the swap? I know the headers will be hard to get ahold of, but couldn't I just use a GN setup? The AC thing I am aware of, but will that mean that I can not use the GN headers and have to use the TTA ones? The motor mounts I am looking to purchase from HRPartsnStuff; will I need to drill new holes into the crossmember to get them to line up? If I use the GN heads, might I be able to use a downpipe made for the TTA from ATR?

The TTA used different heads than a GN did. The GN heads, IIRC, were too tall or too wide and didn't clear in the engine compartment.
You should find out what heads the TTA used before you try this.
