I reviewed several systems for my project before settling on Holley's Terminator EFI. I looked at FAST (not the 2.0 system, it hadn't been released yet), Edelbrock, MSD, and Holley. I liked that the Holley system would control timing with HEI ignition, and I didn't mind mounting the CPU under the dash (actually preferred it). So far I'm very happy with the Holley system and would suggest giving it a close look.
