I have this idea of putting a Holley GM TBI setup that i snagged of craigslist on an older 327 block. Aftermarket heads cam intake etc etc. Adapter plate for 4 barrel to GM TBI. Can anyone see a problem in his or is it essentially easy to do if you have a good understanding of tuning TBI? I'll update as the project goes on. I'm haggling the block next so if i'm making a mistake with the 327 block and crank....tell me.

It should work, but how hard it is depends on what you have. I have no idea what you mean by Holley GM TBI. Exactly what parts are Holley and what parts are original GM?

I started out with a Holley HP Throttle Body EFI and later converted it to a Multi port sequential EFI. Both worked great.
