I stared with the FAST 2.0 and ripped it off.. It was terrible.. now I do have a big cam in my 383 and pull only about a4 on vacuum and while its not listed anywhere on the FAST site or directions they require between 8 and 10... However, the issues did not end there... 2 ECU, 2 Tablets, 1 MAP sensor, 1 Temp sender all replaced before the car ever ran. Dealing with FAST was a ling and drawn out process... days to return calls, weeks to get new parts so I just went out and bought a MAP, etc...
Sent it back and put the Edelbrock SteetFire on.. It was not without its hiccups but at least Edelbrock stepped up and went above and beyond to get it working... and its been great ever since... Would not look back in a sec

It seems as though Holley is the popular set up. Great information guys. I do appreciate it very much. This is my winter project along with rebuilding the transmission and paint and............ it never seems to stop.

At idle I see a 0.5 ratio difference. 14:1 vs 14.5-14.6:1. It evens out at cruise, about 0.2 difference.
But I'm only measuring each bank. I'm sure I still have individual cylinders with even larger differences.

It probably not possible to run 2 O2 sensors since I have not seen it mentioned in the instructions for these units, I have been reading about them online. If you only run 1 O2 sensor which bank should you put it on, or does it matter?

With MPFI, that would definitely be best. With TBI, I can't imagine the computer could compensate well enough as there really isn't a lot of control over which injector goes to which bank.

I am going to put fuel injection on my motor a 327 mild build somewhere in the 350hp range. was on line looking at all the FI kits. Holley,Edelbrock,Fast EFI, MSD all have one. Anybody have any knowledge with one of these kits? likes, dislikes. I am leaning towards the Fast EFI master kit.

I went with the MSD Atomic system firstly because it is the only CARB approved smogger car system. The second reason I went with MSD was for a unified system including ignition controller, distributor, and of course the throttle body. So I'm all-in with MSD - even the plug wires.
So far so good. The injection delivers what you would expect... perfect cold engine performance and perfect acceleration and cruise.
Very adjustable through its handheld controller.
The install at the engine was easy... running the dedicated power and ground wires from the battery was difficult. Installing the fuel pump in the fuel tank was difficult.
I'm $3k into the system and it is worth it. I would rate it the second best mod after the 2004R four speed transmission.
Best to all...

Why not consider an old TPI? Especially with a 327, where you will be down a bit on torque. With good heads and an aftermarket base plate and runners you can have a very nice street machine.

If you're tech saavy you might want to check out megasquirt. It's an open-source ECM and is the best buy around for the money.
Basically, you just get OEM fuel-injectors, intake manifold, sensors, fuel rail, etc, and control it with a megasquirt unit. It can also be setup to control ignition, and 1000 other things (fans, alarm...) if you're so inclined.

With this setup you can do an EFI conversion for around $700.

Tbi?
Has anyone considered a TBI system as this one? The price seems alright for an all-in package.

There are lots of options out there to look over and read about, and i think i have looked at all of them 
But i have made a decision and i am going to go with the Edelbrok set up. I do not believe you can actually go wrong with any of the aftermarket units out their.

There is also a company called EBL that will take a TPI ECM and modify it to allow a computer to upload the numbers from the ECM to its tuning software and allow you to then download the updated tune to the ECM. The later speed density TPI ECMS are more powerful and I think they might have 16 bit resolution but don't recall for sure. The EBL now seems to be the most popular choice for tuning a TPI ECM. My husband wants me to go to a Megasquirt ECM but I've decided to use the TPI ECM because it already has a factory tune a person can start from rather than having to come up with numbers from scratch. Also, there is a tremendous amount of info and expertise on TPI tuning readily available. PM me if you want a link to it.
