1994 Vortec "W" cpi engine?

hi;

i have a 1994 S-10 blazer with the "w" code, cpi vortec engine, this is the 'spyder injection' engine. has anyone successfully changed this intake to a carbureted intake and has it worked? did u purchase an intake from edelbrock who is the only one who sells a direct replacement intake for this vortec, or did u use an early version intake and use spacers to install it on the vortec? if so, where did u get the spacers and what distributor, intake and carb did u use and did u need to make any other modifications to make it work?

please, only answer if u have done this job with success before.

thanks.
