6 pack efi

[jordan]

I am thinking of removing my six bbl set up and converting to a F&B 6bbl FI set up.  While my car runs good most of the time, I can't seem to get the timing right.  If the weather changes, gas changes, or I have a passenger, it seems like it has pre ignition and pinging.  But when I am by myself, on the right day, it runs great.  Also, my carbs seem "on-off" when I try to do some finesse driving.  The "on-off" may work for drag racing, but it certainly upsets the chassis when auto crossing or working a curvy road.  My thought is that the EFI can possibly increase my MPG,  have better drivability, and the computer can get my timing correct, always.  I also think that it will not hurt the value of my car.  It cost a good chunk of $, but I think I will be able to get the money back out when Im ready to sell. 
  I haven't called F&B yet to get all of the specifics.  I am wondering if FAST has an electronic distributor that adjust timing as needed by the computer? I believe I will need the retro fit intank fuel pump.  It appears that F&B is using a Indy Mod Man intake that is MPI, which is better than TBI, correct?  Is there anything that is incredibly difficult about installing this system?  Are these new FI systems truly plug and play?  Do I need an EZ system, or something more elaborate?  Does the FAST system do away with my ignition and coil?
    I would appreciate any advice on this subject.  The frustrations of having my car not be exactly the way I want it has me thinking about selling it.  That would be more costly than just fixing it the right way, and I get to keep my Cuda. 
    I am interested in these if it doesn't turn out how I need it  [url]http://www.ultimasports.co.uk/Evo/Coupe

70chally440 on here is converting his 440 6 pack over to the F&B and he has the same on his 416. Also talk to FASTMAN EFI (Rich) on the web,has a good blog, I'm going FAST XFI TBI, havent installed it yet but looking forward to it, its mostly plug and play but a bit of time is needed for the install, I originally bought an Aeromotive Phantom pump to install in my new factory tank but have since just purchased a TANKS INC set up and sill sell the Phantom and new tank off. I have purchased the FAST dual sinc dist as well as the FAST ignition module so for simplicity, its all the same so the components should talk to each other without issue, that said, I'm not seeing others having issues with mixing such as MSD/Holley and so on either, its just my OCD. Going to EFI may or may not sort out your pinging, i'm thinking it might make it easier to sort out though. Just on the EFI, use push lock fuel lines and fittings not braided unless you want the "look",  push lock are a lot cheaper and work great

just my thoughts, I'm no EFI expert, far from it.

I would do this for sure !
 MPI is far better than Tbody
I used an SDSEFI computer , awesome system comes with a handheld tuner you can use in the car while driving so you do not need a laptop to tune with ,
. You can control timing in 250 rpm increments all the way up in rpm so pinging will be eliminated , it will control additional fuel with vacuum drop like a power valve & accelerator pump  but with more adjustability as it is not either open or closed but will add more enrichment as the vacuum drops lower , it will control choke feature adding additional fuel reducing as the temp rises , 
 I used 2 inline Walbro fuel pumps with a dedicated 3/8 line to each rail & a 3rd 3/8 return line from the regulator but you can do in tank as well . I plumbed the whole system using JIC fittings , a $30 AN fitting is $4 in JIC !
 The best system is Crank trigger , have 4 magnets mounted into the damper exactly 90* apart use a pick up near the damper & this is the most stable timing you can run , then use the dist only to send the spark to the correct coil or you can use a 4 coil system & eliminate the dist completely but you still need a plug to hold the oil pump drive in place .
 Drivability , Mileage & power will al increase as you will always have the right amt of fuel right behind the valve & you can control timing perfectly at any RPM unlike a dist , the dist is always compromise .
 I expect you will be between $4800 -6000 to do the whole set up but worth it for sure , I want to do my car too .

Thanks Neil!!!  All the things you say is everything I wanted to hear.  I have more to read about now.  Im sure I will have more questions heading your way before I purchase. As far as cost, I think it will be worth the investment.  And I can sell off my old carbs and manifold for a good chunk of the cost.  Do you think a self learning system like Crash mentions may be better for me since I am no expert on fueling and timing?  I am not very savvy with computers, and think a handheld would be easier to uses.

I will get to doing some research tonight. Thanks for the help

Glad to help
 self learning could be an advantage or not there could be more left in it if you know how to tune it may also limit other choices . for me it was no question I wanted to be able to adjust the tune & SDSEFI will get you close they have done this before ! I really like the included programmer with SDS , toss it in the glove box , connect ti & change while driving so you can cruise at a given rpm & adjust timing or fuel at that RPM !! COOl !!
