I was originally going to build an LT1 for the same reason some of you guys are. I found out a few things about the LT1.
First off the electronics are ok. For approx $500 you can get a used DFI. For about $1200 you can get a Gen 7 DFI which is night and day superior to the 94-95 LT1 electronics everyone wants to run. Next issue was the cylinder heads. For an LT1, aftermarket heads are almost non existent. The stock aluminum heads wont take much boost before lifting a head gasket as the decks are rather thin.
The last issue was the Optispark. Once you start making power, you will find its output severely lacking.
I explored every option on putting an LT1 together. I even have one sitting here in the garage if anyone wants to buy it.
What I decided was to use was a late model roller cam 350 block.
I have the choice of just about any cylinder head, can run anytype of distributor, dont have to worry about the jerked off accessory routing or replacing expensive Optisparks when the water pump starts leaking. I do have an LT1 intake that I modified to fit an earlier small block that I may or may not use.
