EFI System - Do you know this one?

Steve,

It's hard to tell without seeing a closeup of the throttle bodies but it looks to me like old TWM throttle bodies and fuel rails on a Hall manifold. TWM is now Borla Induction. 

Thanks David. The ECU that goes with that system is probably pretty old. I’m wondering if something like the Holley Terminator X would be compatible with this EFI?

Steve, even if you have the old ECU, I wouldn't recommend using it. Yes, I believe the Terminator X will work but on an IR system, the Dominator is recommended. It utilizes two O2 sensors out of the box (one per bank), as well as a ton of useful inputs and outputs. I'd also recommend separate cam and crank sync triggers for the sake of reliability. Those dual sync distributors are notoriously unreliable.
