Are they the same for the 300 302 351?
Would the starter from a 94 351 work in my 90 300?

 

Dependent on transmission.

Mines an m5 and the 94 is probs an auto.
Guys real nice so I imagine I can just grab it and compare.
But didn't they start putting the solenoid on the starter in 92 or somethin?

 

Yes, but you can work around that. If it is an M5OD starter on the '94, just connect the cable to the load side of the RELAY, not solenoid, and be good to go.

I guess I will have to look at it.
My starter is the original that's been rebuilt countless times
253,200 miles and it's ready to die.
If it weren't for this 351 starter being cheap as dirt I wouldn't bother.
Would the starter from an auto be completely different?
And Thanks for the help Adrian.

 

Correct on the solenoid part. The way I see it, if you were to use a '92 0r later starter on your '90 you would have to put the large battery cable that goes by itself on the solenoid bolt closest to the battery(this is the cable that goes down to the starter) on with all the other cables on the solenoid bolt farthest from the battery. THEN you would have to run an about say 12 guage wire from the solenoid post that you removed the large by itself cable from, and run that wire down to the starter also. ARE YOU CONFUSED? I SURE AS HECK AM AFTER TRYING TO WORD THAT.

This is assuming that all the other parts of the starters are the same and you can swap them anyway.

 

Yeah I am sligggghtly confused, but I do better with parts in hand than sitting here over thinking it.
It's not like a starter for my truck is expensive anyway, rebuilt at advanced is like 40 bucks with core, but a very cheap or free one is better right?

 

I think you will find that MT and At starters are different.
IIRC Ford uses different ring gear tooth counts on MT flywheels and AT flexplates resulting in the starters being at slightly different diameters with respect to the mounting

 

Any idea on the number of teeth on an auto flex plate?
M/t is 164
Where the hell is steve and his diagrams.

 

No. You just skip the RELAY by connecting to the load side like you said, then the relay is basically abandoned.

Why is this so hard for people to understand that every relay contains a solenoid, so calling it a solenoid defeats the purpose of the term relay? A solenoid is simply an electromagnet to actuate a shaft. A relay adds the switch function.

And then my brain melted.
Oh and the flex plate from a 94 auto is 164 tooth and my flywheel is 164 tooth. I counted em one by one before I put it in.. just kidding.
So it all depends on the nose cone, which can be changed anyway, and me taking the time to understand which relay/solenoid/switch/banana to skip.

 

I'm still confused(sorry to use that word again). The RELAY you refer to: is that the one on top of the 1994 starter, or the one close to the battery(which I called a solenoid) on the 1990?

 

Yes they are both relays, but the fender mounted unit serves different purposes on the pre 92 and '92+. Pre 92 it powers the starter. 92+ it powers the electrical systems on the truck.

yea u gotta change the cone the automatic starter if u put it in the way it is the bendix drive will not dissengage the flywheel if u look at them side by side the manual sits down further into the starter

 

I think I got the electrical part of using a '92 or later starter on '91 or earlier truck. Just run a wire or metal jumper between the large and the small electric terminals on the '92 or later starter. Then just hook the large cable on the large starter bolt as you normally would.

This would be easier than the idea I gave under No. 6. Sorry adrian if this is what you have been trying to tell me.
