What's the reason for wanting to $h!tcan the existing EFI / intake? Did you install too much engine for the existing EFI to handle?
I for one appreciate the operability / drivability / tunability / reliability offered by the stock EFI system, as well as the deep knowledge base on how to maintain it. Then there's the swap to the 0411 ECU, which offers improvements over stock (and which I haven't done,
but I know it's
out there).
I can see a carb having it's place, but if you've already got a functioning EFI and there's no
necessity to change to a carb (e.g., "too much engine")...
Heck, even if your EFI's
not functioning, the route to repair it is well paved and all the 'abilities it offers are retained.
I've got an Edelbrock / AFB on my Camaro and too often I have to clean out the idle air bleeds or remove the growth of bacteria (or some sort of greenish yuck) that takes up residence in the fuel bowls.
