Re: [Amc-list] EFI on 195.6OHV...

Yes Mark, I made a 2x1 intake (plate) for a pair of Carter YFs. Just found it a few months ago along with the cobbled (but well working!) throttle linkage. Think I offered it to the list for shipping and handling charges -- if not, I'm doing it now! Just send me an address if interested and I'll see what it would cost to pack and send. 

The 4.0L injection system would be hard to work with. The distributor (camshaft position sensor in it) and CPS would be troublesome at best! If you really want EFI the simple solution would be to use a throttle body injection system. Easiest would be from a 2.5L GM four (one barrel, I think it's about 2" in diameter, maybe a little under). Just get it from one with a distributor (pre 86 cars, I think S-10s used the distributor through 89 or so). 

Want to keep it more or less all AMC? Use the TBI system from a 1985-90 Jeep Cherokee or go with the smaller Renault Alliance 1.4L unit. Even the small unit should flow enough for the 196 -- that little four turned a lot more rpm! But there's a catch with the Renix units -- they use a speed sensor that is actually a mini generator. It uses a pickup coil that creates an AC pulse signal as a notched flywheel passes near it. I would think Tom could figure out how to duplicate the square wave signal electronically from a tach signal taken from the coil. Since it's a constant fire (always open) single injector there shouldn't be any wide notches like on the 4.0L multi-point system. I don't recall -- never paid that close of attention to the Alliance I drove until I got it paid down enough to trade in without losing a lot of money! The speed sensor did get dirty and cause rough running once, so it's a must have. 

The 1.4L with an auto trans was great around town (surprisingly!), but on long trips in relatively hilly country it was too much work! Had to run up to 75 down one 1/2 mile long grade to get up the other side and still be doing around 60 near the top! Not a steep grades, just 1/4-1/2 mile long. Several though GA and SC on I-20 between Atlanta and Columbia, especially withing 50 miles on either side of Augusta, GA (Savannah river valley). 

Yeah, I'd own another, but not as my main car!!

It just occurred to me it would be really easy! The top of the manifold is 
a simple plate aluminum plate with a carb flange. Mount an injector over 
each port (1, 2+3, 4+5, 6), megasquirt controller. Improved mileage 
wouldn't hurt... would be easy to turbocharge.

Frank said he had made a dual manifold, so You should be able to do much the same.
 A simple plate drilled and machined for injectors angled as close to the intake ports as you can get them.
Or bungs welded to that plate or an original manifold.
  Your working with a delco dist so getting it set up for efi should not be too big a deal.
The realy lowbuck approach would be if the damper setup from a 4.0L could be made to work, Using it you could then approach it as if you were injecting a 4.0L. I laid out machining a v-belt damper for the CPS to work with H.O 91-95 injection. You could do the same to a 196 damper easily. Now getting the dist stuff to fit may stall you. That is needed to fire the injectors on an HO system.
