I have read the above posts with interest (and some confusion!). I have had plenty of issues with my Holley carb and I am seriously considering going to an 8-stack EFI. I'm running a 427 iron Dart block. When it was last dynoed about two years ago it was just over 650hp, but it's certainly not that now and is due for rings/bearings, a top-end refresh and a tune - so thought I would do the EFI at the same time.
Can anyone suggest a sensible 8 stack EFI option? I'm in New Zealand so Australian or NZ product would make sense but there are so many options out there. I just want the car to be mild race tune, and still streetable.
