A thought...

[Michael Manry]

This may be overly simplistic for this forum level but......
ACCEL makes a "universal" TBI setup that is good for up to about 300HP. 
It uses four 45lb/hr high-pressure (3 bar) injectors and all of the 
sensors etc are stock GM stuff. Using their CALMAP software, you can 
adjust just about everything but your tire pressure. I used this system 
on a Buick 215 V-8 sand car and it worked great. You can get the whole 
works for about $1200 from Jeg's or Summit.

Hope this helps
