Need INFO on convering my LT1 to carb

Tired of efi and want something new. Anyone do this? Can I get the 4l60e to become stand alone. I know there are kits out there to convert the Ls1 to carb but are there kits to convert the LT1

Well, youll need this:

And one of these:

You can get some tape that goes around the balancer to show timing in degrees, plus some kind of pointer so you can set the timing.
Also a regulator to reduce the fuel pressure to carb levels, Im not realy sure if it can be done with the factory fuel system, maybe a TBI system since it works with pressure similar to a carb.

What are you going to put this in? I realy dont think you can get the carb to fit under the cowl of a 4th gen without serious modifications.
