I need some help with a manifold question.
I have a 292 Y block in a 58 Skyliner that came with the stock 2 barrel intake.
My father and I decided on installing the MSD fuel injection kit.  This required a 4-barrel intake.
We bought a ECZ-9424B intake on it but wondering if it is actually compatible with the 292 block?  
I ask because its running terrible! We have been beating our heads against the wall for months.  
Heavy dark carbon on the plugs, loading up and backfiring, feels like a vacuum leak.  We've checked, checked and re-checked everything from plugs, to gap, many timing changes and adjustments and confirmed firing order.  Everything is checking out but no power over 1/4 pedal.

So bottom line question is, does the ECZ-9424B manifold work on the 292?  I dont believe it was ever offered on the 292 so not sure if the head and intake runner plane angle actually are the same.  I know they bolt up but not convinced they actually work together.  If anyone could give a definitive yes or no, it would be appreciated!
Thank you!!

Yes, the ECZ-B will work on a 292. If any doubt, simply compare head/intake with the intake manifold gasket.

It sounds to me like there is too much fuel pressure. Have you verified with FI pressure gauge? Is the fuel system plumbed as per instructions?

____________________________

The ECZ-B 4V iron intake manifold is compatible with all 1957 and newer cylinder heads.  The ECZ-B manifold was optionally available on the HD 292 truck engines thru 1964.  It also works on the 1955-1956 cylinder heads although those '55/56 head ports are dimensionally smaller.  The '54 heads have considerably smaller intake ports and those heads do have a problem with any of the later model intake manifolds in regards to intake manifold gasket seal.
  
The obvious problem to watch for is intake manifold gasket leaks as the manifold must be seated square to the gaskets before tightening it down.  If you haven’t pulled the intake manifold back off the engine since first installing it, I would suggest doing so and check the flanges on both the intake and the heads in detail.  Although the previously installed gasket will likely shred when removing the manifold again, look at it also in detail.  The intake gaskets are known to slip or double up when putting the manifold in place so be sure to look at the gasket in detail when removing it.  The intake gaskets are left and right side specific but I have seen them installed on the wrong sides which can be a problem all in itself.  Vacuum leaks at the carburetor flange will also confuse the unit.  Be sure that the throttle body has a full gasket seal at the intake manifold.  The ECZ-B carb flange can be picky on the gasket that seals the unit to the manifold depending upon the base of the carb or throttle body that's being bolted to it.
 
Beyond all that, the distributor and the fuel injection unit are also suspects.  Be sure to use a timing light to insure the distributor is advancing as it should.  Assuming you have not done so yet, call MSD’s tech line and let them know the symptoms.  Vacuum leaks and header leaks are at the top of the list for fuel injection tuning woes.  Any kind of exhaust leaks prior to the oxygen sensor will drive it crazy and make for a abnormally rich mixture.

Thank you for the reply's.

Yes, fuel pressure is set according to manufactures set points.  The system has been checked twice now to ensure everything is installed according to MSD instruction.

Exhaust system is new and does not show any signs of leaks.

This car is a fresh restore/rebuild by my dad and I.  The engine was rebuilt locally by a very reputable builder.  He ran it on his test stand for hours and seemed fine with a 2 barrel carb.  Once installed in the car, ran like a 4cyl, not an 8.  
We then upgraded to the MSD kit and now we cant get any power at 1/4 pedal or more. Idles nice......for a while.   Plugs, gap, timing, gasket compression was all checked.  Looks like we had good seals last time we pulled the manifold to verify.

We are going to try a new set of plugs and new intake gaskets one more time.  We are using a Hot Spark ignition module instead of the old points.  Coil was matched per manufactures specs for the hot spark.
We are not convinced there isnt an issue with the distributor.  It is the original that was in the motor when we got it.  We never had it balanced or tested, just installed the hot spark and put in a new vacuum advance.  
We were thinking of trying a new HEI distributor but cant seem to find one for a Y block.  I only found this one on ebay and not feeling the warm and fuzzies with it.

Any thoughts?

Speedway motors has MSD units for the Y-Block. The "cheap" ones online can be copies from China and are trouble. For street use I'd go with the one with vacuum advance. 

Y's guys rule!
Looking for McCullouch VS57 brackets and parts. Also looking for 28 Chrysler series 72 parts. And early Hemi parts.

Ill look into them.  When we talked to summit racing, they told us MSD did not make one for the 292 Y Block. 

I found this one.

Does anyone know if it has the flat/slot style key for the oil pump drive shaft in the bottom of the distributor?  Ill need to pull ours one more time but i dont think it was a hex key, i thought it was the flat blade style.
I dont see anything listed in the specs about it.  

It will be a hex drive.  A 292 would not have had the blade style but parts are interchangeable so if you do have one, simply replace the oil pump and drive shaft to match the distributor.
Whoever you spoke with at Summit obviously did not check their own site or any catalogs.  MSD produce 2 distributors, pro billet, which requires an external box, part 83831 and ready to run, which does not require a box, part 8383.  A while back, there were reliability issues with the ready to run.  That could have been addressed by now.

Looks like this is what I want.

This is a ready to run unit not requiring an external control box.  Plug and play.

Anyone running one of these?

A distributor with a flat tang drive says "1954".  A '54 distributor would not have any mechanical advance, only vacuum advance.  They were designed to use with '54 carburetors, different carburetors and fuel injection would not be compatible.  If you do have a '54 distributor, you may only have initial timing throughout the rpm range.
