It can be done but all the ones I've seen 'done' ended up so hacked it made ya wonder how they worked at all.

So your trying to install a '98 TBI set up on your blazer?
Are you using the vortec heads/manifold assemblies?

What about using an after market wiring harness?
Have you looked into that?

Makes for a pretty simple plug & play installation with one of those.

What are you doing for fuel delivery?
In-line electric pump or are you changing out the tank for one that has an in-tank pump and baffles?
