LT1 Swap Update
Finally getting underway after replacing head gaskets, intake gaskets, etc etc.
Here are some pics of the install process, along with a pic of where I notched the motor mount.
I still need to install the trans, cut the hole for the shifter, put on the fuel lines, ps lines, ac line, electrical, etc.
I've got Z28***** building me a custom plug and play harness which should be done soon, and I'm going to get my PS lines yet... A/C lines will be a bit later as I'm ready to have this car running!
Oh and I originally planned on going with the A/C bypass pully to save myself the trouble of notching the clamshell and banging up the k-member.. but I lost the bracket! So I said the hell with it and did what was necessary to make the A/C compressor fit.. At this point I'm pretty sure I did the right thing, and it was very easy!

Hope I don't **** off the mods... 
Oh by the way -I did NOT like trying to install the motor from the side...and I dropped it on the fender!! I ended up with a tiny tiny little dent in the fender to drive me nuts forever, but ended up installing the motor from the front.
It took me about 3 attempts to get the k-member "massaged" to where the compressor would clear and the mount would seat.
I also got help from a thin friend to drill the holes for the master cylinder in the firewall - I couldn't move around worth a damn under there...however he managed to do the job while talking on the cell phone.
By far the most difficult part of the swap for me so far has been putting the clutch pedals and master cylinder in. The only other thing that really held me up was getting new head bolts, head gaskets, intake gaskets, etc.
One thing I did find out was that GM head bolts don't include washers - which you need for aluminum heads. The gm washers where around $1.17 each so I sent back the head bolts and bought the arp kit for like $65 shipped.
