Hello, I'm new to this forum. Im looking for info on a Holley sniper EFI set up for my bird. It has a built 400 all Dyno tuned. It currently has a Holley 650 on it and it needs adjusting frequently. I'm considering doing efi. The motor was built by a decent machine shop motor builder. To my knowledge the engine is 450 hp. Does anyone have any suggestions about the sniper application for my car? Thanks
