because speed density efi has strict cam rules. that motor being a car motor and probably an old one at that ran a cam that didnt follow such rules and there for will not play nice with the computer causing engine running issues.

the 5.0/5.8 have the same bellhousing. the AOD will bolt up to the 5.8 just fine i know because i have done it along with many others. you just have to get a crownvictoria 5.8/AOD flexplate is all.

now have you been over to Full Size Bronco . com? there is a lot of guys from Eugene on that site and could potentially help you and steer you in the right direction. the mechanic that told you those things doesnt know fords apparently. pull this motor your have now and get your money back then take your motor and have it rebuilt or buy a wrecking yard low mileage motor. you have plenty of places in eugene to shop from and these motors would be complete and correct. this would give you time to rebuild the old motor you have or not. my 5.8 swap i did many years ago was a wrecking yard motor and it ran awesome for many years till i rolled the bronco.

 

This engine was rebuilt from the crank up so I'm told. The crank was ground and pollished but everything else is brand new. It has an aftermarket cam in it built for a truck so I have the lower and mid range torque I need. I don't know the brand yet or a part number so I have no idea about being ground for EFI. I know the guy is coming down to help me with some of these problems on Sunday. I'll let you know how that works out. For what it's worth, the guy runs the tech lab at one of the local community colleges for the automitive technology classes. I'm inclined to believe he knows a little something. I just have to get him to research it for me.

I will also check out and ring a few bells on fullsizebronco.com to see who says what on there.

I hope you won't take this personaly, but since we are in an internet forum and I don't know you from anyone else, I am going to check on the things you are pointing out since I don't know your quailifications and experience and such. Again, don't take it personal, I just gotta be absolutely sure before I drop one of these engines in my Bronco because I can't afford the time, money or stress of any more complications.

If you have any specific web sites I may research to find out about the cam and EFI issues, please post them so I may become educated myself.

Thanks to all for taking the time whether your information is good to me or not. It's all worth chewing on while doing this project.

 

Another guy here that has done a 5.8/AOD combo BTW...

As for the above question, the SD EFI system relies heavily on a strong and steady manifold vacuum signal so cams designed for this system will have some unique characteristics related to duration and overlap. These SD cam characteristics also tend to compromise peak HP potential so you simply won't find them in a carb based cam profile.

 

Ford Fuel Injection should be able to answer most if not all your questions.

call this guy and ask him to give you the specs. the important factor is the lob seperation. if its less then 114* then it will run like poop. Search for 351w swap on this site, you will see my feedback echod many times.

good luck.

 

Thanks Kem. Finally something I can sink my brain into. I'll get back to you on the progress.

 

Please see my new thread - 302 SD EFI to MAF swap

 

Of course reading got this guy there... MAF!.

 

Problem solved! The rebuild is going back and so is my engine for a rebuild. See my other post "302 SD EFI to MAS swap" for details.

 

Latest: My engine had all bent valves and a cracked head. After finding another good head the rebuild is on and I should get it back this weekend. Don't let anyone tell you that a Ford 5.0L 302 is a non interference engine. The guy doing the rebuild said the engine was almost done anyway. The cam bearings were all shot and it was just a matter of a little more time before detination.

 

bent rods can happen many ways. not just from contact with the pistons. did he say thats how they where bent?

 

Yes, he did tell me that there was evidence of contact on the pistons as well.

 

interesting

 

Latest update: Picked up my engine on Sunday. As of tonight 6-29, it's back in it's nest and bolted down. Now to hook up all the spaghetti and hope for the best. I saw some of the damage. The valves clearly hit the pistons and they were bent. The pushrods were bent as well. The cam bearings were toast and would not have gone much longer. It's just good that I got it rebuilt now rather than having it crap out on me in the middle of nowhere during hunting season or something like that.

More to come.

 

I hope you got a nice double roller timing chain this time. Stock plastic gear teeth suck, and replacement steel gears with single row chain sucks too. Cam(and ignition) timing is critical, you gotta spend a few extra bucks to make sure it stays correct.

 

I am not sure the exact specifics on the timing chain he put in but I know it's a performance part and it's all metal, no plastic. As far as the cam and the timing, the cam was supposed to be matched to the fuel injection system requirements and the timing is 10 degrees btdc without the spout connector and the computer does the rest.

We'll see how she runs on Tuesday afternoon when the guy who rebuilt it comes down to be here when I fire it up. If there are any problems, he will be here to witness it and it's all on him to make it right.
