My 351w Explorer EFI conversion thread

[tasker]

i'm a Ford parts guy if you need anything give a shout as well....watching this as i am doing 351 EFI on my project rig

 

[pa69broncoguy]

Thanks Tasker, I'll keep that in mind if I get a tough question. Its suprising how many people are doing or thinking of doing a similar conversion.

synchronizer

I got my cam sensor today from work, it came through right. It ended up being part number DA-2069 or F6TZ12A362-CB on the box. The housing has a number of F6TE-12131-DA cast into it, I was told the casting number is only a production casting number and not an actual synchronizer part number. I never knew ford called a cam sensor a synchronizer.

 

[pa69broncoguy]

The other night I gathered up all the things that I needed to send for efi guy. I had been waiting for my cam sensor so that I could have him set the timing on it. So here is the final list of what I sent.

Complete engine harness----98 explorer

Transmission harness (for the o2 sensors)----98 explorer

plug and pigtail body side----98 explorer

2 computers ( just in case)----98 explorer-both

cam sensor (so garry can time it for me)----96 thunderbird 3.8

obd2 port (with as much wire as i could get) ----98 explorer

rollover switch ----98 explorer

relay box (possibly can be used in the harness)---- 98 explorer

explorer balancer

I got my explorer balancer back today from dampner dudes. It looks good. they said it was good shape and would be good just getting rebalanced. They have a really quick turnaround, very nice people too. They even cleaned up the seal surface and gave it a coat of paint. It cost $50 to rebalance and another $15 to ship it back to me. I didnt htink that was bad. If anyone is thinking of rebalancing i give two thumbs up for dampner dudes;D;D

I am following this tread. great deal of info so far. keep up the good work. when I get back in the country I will be starting back on my bronco. I am doing pretty much same as you. 351w with explorer setup with the obd2 efi.

question, the above cam sensor. did you find a direct drop in? or do you still need to machine the top mount to fit the hole for distributor? I didn't think there was a direct drop in cam sensor. if it is that's awesome...

Nope sorry its not a direct swap i sure wish it was, this sensor will give you the correct oil pump drive hex so you will be able to drive your oil pump. I have been told that you should use a longer oil pump hex shaft, ill try and post a number when i get to that part. A collar will stil need to be machined to adapt the outside of the sensor to fit into the 351 block. Lars has done this before with sucess so that is where i found the info on getting this sensor.

Im glad the thread is helping you out. This is my first install thread, my whole purpose is to try and put all the info i can from the swap on here to try and inform and of course be informed of the issues involved and solutions. I know the info on here from people like efi guy and lars has motivated me to do this conversion so hopefully this info will also help you and other people in the future with their swaps. Good luck with your project, Jason

sweet deal on the damper! might have to do that myself

Yeah it worked out really well. It was out balanced and back in around a week. They told me on the phone they do same day turnaround on them, and they actualy do.

I am in the early stages of this same build just got my lightning lower and explorer upper scored of craigslist in san fransisco 350.00 plus 50.00 for shipping and he threw in 24#injectors and a maf,tomorrow i will be getting the harness and cpu and the trans harness and fuel rails.do you any short cuts you can recommend for getting the harness out is a bit chilly here not sure i can get it out in one day but im going to give it a hell of a try thanks for the write up it is helping me learn alot.

Dont forget to take your torx bits to remove the top cover plate possibly a cordless drill if they strip. Removing the whole upper intake will make fuel rail removal easier. The engine harness /cpu will not be terrible just a but difficult to get the crank sensor wiring out, go gentle with the sensor plugs i have heard they get brittle. The trans harness is tough to get out. They attach the harness a couple places to the trans, very tough to get loose just because space is minimal. The trans harness plug is also quite large and tough to fish up through past the firewall, It sounds like your off to a good start. Good luck on your parts trip.

thanks for the tips i got just about everything at the yard today. my dewalt cordless sawall made short work of the floor of the explorer, the trans harness was easy to remove from inside the cab i recommend doing it this way save alot of time. what are you going to do with the throttle cable not sure if i should have grabed that to,what valve covers will fit i have stock 88 heads with procomp roller rockers i have the bronco script older valve covers there a little taller than the 5.0 explorer would they be a better a better fit. thanks marv

Wow thats a good day at the u-pull it, I need to get one of those cordless sawzalls. Im not sure if you will be able to use the taller valve covers. I dont think there is very much extra room. Im not sure what i will do with the throttle cable. I saved the stock cable but i doubt i will use it. If i remember right it has a special end for the explorer petal and the explorer petal is cheesy looking plastic.

Not sure what you were running before, but you can run the explorer TB with the mustang linkage on the butterfly.

 

[pa69broncoguy]

I had the original style linkage modified for use with the edelbrock carb.

What is your plan for smog testing that thing in PA that's if you even have to,here in Reno nv they require that you have to have all of the smog equipment or components of the motor that's to be swapped in Im going to look into that tomorrow at the DMV I hope it's not a dream killer for me but I'm going to do it anyways,

 

[pa69broncoguy]

so far pa has been good with emissions. We dont have to have vehicles sniff tested in most counties, all we have is a visual inspection. If your vehicle didnt come with it originaly it doesnt have to have it, doesnt matter how new the motor is thats in it is, the registration says 1969.

 

[mjramacher]

i checked with the local dmv emission lab in reno he told we basically what you said in your last post all a 71 need is a gas cap and no visible smoke from the exhaust no matter what motor goes in.im feeling much better now about all of this, time to build this M effer

 

[pa69broncoguy]

I went and picked up my cam sensor bushing today. I had a local amish machine shop make it for me. I am impressed with their work , I think it turned out good. It ended up being $74.20 not super cheap but a custom machined part seldom is. Here are some pics.

How did they get that piece of wood to look like aluminum?
