This link should tell you all you need. I didn't like the way you have to run the remote thermostat, but thats just me!

I've got a friend who has one on a built '85. He's very happy with it and it's a strong runner.

Search on the THIRDGEN.ORG forum. Few people tried, even fewer got it to work successfully using a converted LT1 intake..
Good idea, I'd be doing it if it didn't mean no Emissions, chances of eaten distrbutor gears and coolant leaks, remote thermostat
, need for smaller distributor, etc..

I have a conversion, I did most of the work myself with the exception of welding extra metal around the water jacket for extra insurance (no leakage) the advantage of a conversion is to allow the engine to pull more air at high RPM, if you have head work and a higher revving cam you will see a BIG differents. I pickup 5 mph in the 1/4 doing it, which result in 50 hp or more doing that.

I am in the process of doing the same thing. Randy, how did you get the bigger distributor to fit? Did you machine the egr ports off? I am considering doing that because I don't want to set it up for remote coil application.

Working on one at present.
If you cut away EGR boss completely you only have to cover a hole 1.5 x 2 where the exh gas went under the runners.You will need custom lines ( a -AN fitting on each rail )with the large HEI as the large cap won't clear the stock lines.
As above I am going to weld extra material above the stock water jackets as there is little room for error and the LT1 manifold is a lot lower than stock in these areas.
