I don't know if Holley will support the old Accel EFI manifold? B.

I don't know if Holley will support the old Accel EFI manifold?

Why wouldn't Holley EFI work on this intake manifold? It's an aftermarket engine management system; operating the fuel injectors & controlling the ignition timing.

Yes it does. I'm currently installing a HP EFI for this manifold & LT1 engine. Any EFI Gen 1 manifold will work, but would require modifications for different LT1 head bolt fastener locations, and a remote throttle body. This can be done. This was the only solution for the old Chevy LT1 manifold replacement (1997 Camaro SS Gen4 app).

Fuel injectors: 95 lb/hr low impedance EV1.
Ignition timing: Optispark eliminated. EFI connection 24x & single cam pulse installed with Coil-On-Plug change. Distributors will not fit under a 4th Gen cowl.
I'm new here. Thank you for response. B.
