nah these are direct replacement tbi efi units by FAST EZ-EFI. they self learn and while they do have a lot of CFM, they curve everything and learn over time how to handle the car based on inputs you select. its idiot proof. all of the hot rodders do this now over carbs.

as for the spacing...they are identical to the carbs, air cleaner would bolt right down on top.

yeah I know it isn't pure or old school or true to Packard, but I've been having a hell of a time with the carb on my dart and I'm switching over to MSD atomic efi soon on it. plus my Packard is far from pure at this point anyways, while not as bojangled as others. The ignition on it is not stock points either, so meh....who cares if I update to EFI too.

I already have the dual carb intake and the air cleaner. I just happened across this setup because FAST is about the only one that will run dual quads with their ecu unit. everything is self contained, just have to weld a bung in the exhaust for a O2 sensor and obviously no mechanical fuel pump.

even the new repo gas tanks have a drain bung at the bottom that can be repurposed for a return fuel line.

to get the carbs redone would be about 1600. I can do the efi for under 2800 and never have to mess with it.

I also don't have the correct carbs, they would have to be re-jetted by Daytona to mimic the dual quad setup by Packard. otherwise I'm sure they would be way to much for the motor too.

with the efi it would adjust on the fly for the motor and correct the cfm with fuel. think of it as carb that can adjust itself infinitely (to a point) on the fly and without stopping to change jets one day to the next or having to worry about atmospheric variables.

yeah they have computers, etc, but all of the sensors on this thing are GM and can be bought over the counter at autozone and for cheap.

I think it will go nicely with my cam work and lunati valve springs.

this motor should be capable of north 6500 rpm with the cam/valve springs, but to be honest it is about conversation pieces, because I wont be drag racing or hauling anything with this car. I still plan on using the twin ultramatic.

first dual quad efi Packard v8. sure why not.
