I have to say its one hell of job to get this thing really roaring. We cant get more than 31 degrees of total timing no matter what, and it seems that the engine would like 35ish fore most HP. No matter what we do, theres always missfires above 5000.

What Spark plugs you have? Do you use resistor type plugs as Edelbrock recommends?

No, no pinging. It just doesnt fire properly, like a turbocar with bad sparkplugs, you know.

What kind of plug gaps you guys have? My motor hits a wall if I have more than 30,25 of total timing, wonder if I have too big gap.

Too much dynamic compression means too much cylinder pressure, too much pressure means pinging. I think around 8 would be max for Iron heads. This is what I have now Hughes Engines ....And this is what Hughes suggested Hughes Engines But, I have to say that the EFI works amazingly!

My friend has a dyno, so we decided to spend a few hours to find out whats happening. And seems that I need a bigger cam, engine can take only 30.25 initial timing. And I think thats because of my 8.3 dynamic compression. But, it pulls strong to 6000 and Hp is rising all the way, torque curve is...

Yes, new (rebuild) engine.

Has anyone had any backfire problems? Mine starts to backfire and hesitate when the throttle is over 20% open, and I cant step it WOT at all. Other than that, It works like a charm in idle and runs great with just a touch on the gas pedal.

They say the kit is for 318-360 but I dont know how the big intake ports would work with the small 318 heads.

Yes, seems like it would be a good time NOT to spent all the money in the car, but I have done it allready, and now its mostly work that this one needs.

No they were actually brand new, but I soaked them so bad trying to get it running that they didnt fire anymore. I also noticed that I have 35lb/hr injectors but the setup wizard didnt give that option because I gave engine size 318, I had to change it to 340 to get to choose the correct...

Allright! User error, it works after changing spark plugs. Now Ill just have to be paitent and get it on the road for more adjustments.

Long story short: Engine had total rebuild and the video above was from the setup wizard warm up. Yesterday I tried to warm it up so I could change the oil and check that everything is good, leaks etc. I had massive trouble getting it to start at all, I had to add crank fuel 7% to get it...

Yes the AFR was 10 and that means its not doing anything. Target idle afr is 13.9 and its running far from that, 11-12.5 and thats soaking the engine in gas. How fast should it adjust?

Update: it does measure but it runs so rich that gas is flowing from the pipes and I cant get it leaner.

Anyone had this: Afr says 10 all the time, so basically it means that the sensor doesnt read. Did I soak it at some point? Is it ruined for good?

Cam: Hughes Engines not sure about the vacuum, ill check next time.

Got mine running at last.

What did you do with the throttlecable and the kickdown linkage? How did you guys attach it? Does edelbrock provide an adapter or do I have to make one?

Thanks, I was going to put a diod on the brown wire. Im also doing a magnum swap and Im going to use Jeep alternator so thats a little more complicating than i thought. Seems that the jeep alternator needs a external regulator.

Guys, where did you hook the pink ignition switch wire? -71 Duster so brown and dark blue tr are the sw-ignition wires, which one is "RUN" and which is "start"?? Does it work if I just splice and hook those three together?

Im going to put one on my magnum build. Cant see any problem why wouldnt it fit besides the intakemanifold bolt pattern, but ive got EQ heads with LA pattern.

I was reading the instruction manual and started wondering is the fuelpump harness long enough to reach in-tank pump? Looks short on the picture. (havent got my set yet)

I need to order new plugwires for the edelbrock distributor, what do you guys suggest for a mild Magnum 318?? Edelbrock Spark Plug Wire Sets - Assembled

So.. I can finally ditch the AL6, makes my engine bay alot cleaner. I have MSD Blaster2 coil, it should be fine.

Does proflo4 still need coil for ignition?

Ill find out in 6 months, ill let you know :D

It should be better than carb or TBI, cant think of how it wouldnt be.

This looks awesome, no reason for buying a sniper or fitech anymore when a true MPI is this affordable. Tell us more when you get more miles on it.

I believe it should be 4 barrel??
