I have used the ACCEL EFI system on a 215 Buick powered off-road car and 
had great success with it. ACCEL/DFI's CALMAP software lets you tune 
just about everything short of the color you want the car including 
electric fan control and Nitrous (if you're brave AND rich). They also 
offer an inductive pick-up option so you can connect an MSD 6A, 6AL or 
the new ACCEL 300+ ignition system. All of the sensors and parts are 
standard GM and the system is much more affordable than MOTEC, 
ELECTROMOTIVE, or EFI TECH. I can definitely recommend it.

Hope this helps
