When I purchased the '84 it had a whipped, carb'd 302 with no emissions.
EGR disconnected, no canister and straight exhaust. The engine has been replaced with a '86 302 EFI, converted to a carb with a spacer plate and conversion distributor. The engine runs great when cold but as soon as it reaches op temp, it blows the spacer plate plug off and bucks like a Bronco..pun intended. Do I need to put the EGR system back on it with the canister to enable it to run correctly at op temp? I'm hoping that there is a "work around" for this as I am trying to keep this build as basic as possible for future serviceability. Maybe the pics will shed some light...Any thoughts?
The semi-finished install. New plug wires to follow as well as vac lines.
The canister system just stores the fumes from the gas tank, that's it. The EGR just introduces exhaust gas into the intake for emissions and because of the emissions design, keeps the engine from pinging.
You have some other problem. What's the timing set at? Where did you get power to run the HEI distibutor?
Thanks All for the prompt feedback...It doesn't backfire,just stalls,but once it cools down it restarts.
I'm wondering if I've got vacuum routing screwed up somehow. Does anyone know of a true 84 302 routing diagram I can access? I Googled it but didn't come up with anything definitive. Sorry for the slow response...the '06 Taurus needed a Cat-back exhaust and the '00 Windstar needed a loaded caliper replacement today so I've been a tad bit busy.
I currently have this truck discussed in this thread. The egr is located on the carburator spacer plate. It is capped off. I installed an older model spacer that only had an air hole with a plug but on start up the air pressure from the manifold would blow the plug off. Here's what is happening... on cold start truck runs excellent for about 20 minutes at idle. When gear is engaged it shuts off. The carb throttle body door is not staying open once warm it closes as it was when cold. So to restart I have to hold the throttle butterfly open and it will start again briefly. Feels as if it's not getting enough gas or temp control on throttle is not working properly. I want to illuminate the possibility of the air lines bring incorrectly plugged do you have a simple diagram?
The distributor power was accessed from the existing dist.harness. Seemed like the obvious choice.
There's the problem right there...
Read the instructions that come with almost any HEI and they are going to call for a minimum 12Ga, and possibly a 10Ga. wire with 20+A feeding it.
Do as Dave said and use your old ignition wire to trigger a relay fused directly to the battery or solenoid.
I'll bet your truck will stop breaking up and the timing will right itself.
I don't like this spacer thing going on either. There is no pressure in the manifold, only vacuum. The only place that could have any type of pressure would be a exhaust passage in the manifold for the EGR. If you have plugs popping off, I think there is something wrong with the spacer plate or it's not compatible with what you have. Using the original spacer plate with the EGR blocked off should work.
And yes, you are probably running the HEI off the original resistor that ran the Ford ignition. The HEI is probably starved for voltage.
Till you get the choke worked out, you can take the round black piece of the side of the carb and turn it to make the choke door open on the top.
I think Jim has it right. I remember when I was sharing a power wire for my electric choke with the coil. It caused problems. I got the choke operating off of a 12V relay now and the ignition problems went away too.
Good info! I'm gonna do that and I'll let you know what happens. Thank so much!

I'll do that and let you guys know how it pans out. Good info!
Kristol8178 is My Daughter. I appreciate everyone's feedback and allowing her to . The truck is in South Carolina and I'm in Ohio and it is sometimes difficult to translate without loosing details. She is working hard to get the truck solid so We can get it up north. Again,Thank You to All !
