Nee help on starter, please
in last fall I build my engine and transformed the tired 400 into a muscular 408 with some TMI flattops, headers etc.
Due to a lot more pressure in the chambers the starter has to do heavy work now and a want to replace it with a new one with a step down gear from later models.
The p/n I found on the starter is : C7AF-11001-B
it´s a 1977 400 with C6 trans.
Can somebody tell me a from what type of engine family and car/truck range a starter with gear will fit into my application, please ?
My F100 is in germany and I would avoid to order such a heavy part in the US so I wanna look in the scrapyards or second hand or at least buy a new one but as cheap as possible ....
Any infos are appreciated, thank you !!

Also the powermaster starters are smaller in size which should help on shipping, and they're smaller in design so they don't suffer as much from heat soak like stock starters do on modified engines sometimes. Anyway, it's an option if you don't find a factory alternative.
This would be the choice if I won´t find a second hand starter in my area. As I remember the 400 was released until 1982 in passenger cars and light trucks. Although this is almost 30 years ago it´s not a problem being in the US, guess there are a lot of ´yards that carry 335 stuff.....
... but being in germany it´s a real problem !
For me it would be essential to know from what year on a starter with step down gear was used or - is there a gear starter type of a other (later build) engine family beside the 335 series which will fit to broaden my bandwidth to search for.
I don't imagine 460's are any easier to find in Germany than 400's are...

Perhaps this question makes it easier : does anybody know is there even ANY factory starter with step down gear for a 335/385 series or do I have to go aftermarket ANYWAY ?
This is not the correct A/T starter for a 400.
It was used on A/T 240 I-6 & 221/260/289/302/351C/351W passenger cars.
A/T 240/300/302/351W (1981 and later) F100/350's / 1969/96 302 & 1975/96 351W Econolines / 1980/96 300 I-6; 1969/96 302; 1981/96 351W Bronco's.

You need the A/T starter (with one of the above ID numbers) from a:
400 1971/79 Passenger Car / 351M 1975/79 Passenger Car // 351M/400: 1977/79 F100/350 / 1978/82 Bronco / 1980/82 F150/350 & Econoline.
The M/T starter is NOT the same.

Well, the timing is at 10 BTDC at the time. Last week I throwed in a new special recurved duraspark and the seller advised me to put the timing on 12-14, that would be even more and put more load on the starter.
I want to adjust the timing coming weekend, what do you think is best to do, please ?

That fact that it bolts on...does not mean it's correct.

Ford used the same starter drive in all: 200/240/250/300 I-6 / 221/260/289/302/351C/351M/351W/352/360/390/400:
D6PZ11350B (replaced C6VY11350A) .. Starter Drive (Motorcraft SD302)
The powermaster p/n 9605 ( NOT 9606 as I posted before, sorry ) i. e. has a gear reduction ratio of 4.4:1, I need a reduction for the starter due to the higher chamber compression. The actual starter has not and works really hard sometimes getting the 400 to run ....
Thank you for the infos, you are very helpful !
Some 1970's Lincoln's & Mark's w/460's / 1970's fullsized Ford's, Merc's and T-Bird's with 429/460's have a gear reduction starter.
I see you live in Germany...beautiful country, I've been there twice on vacations. 2000 (Berlin/Dresden), 2001 (Deutches Wein Strasse and etc).
I`ve been in the US to, but it only lasted for New York City, so far..... hope to come again for a NASCAR race and travel some states !
Sorry to ask again but is one of the ID engineering no´s you´ve posted before the gear reduction type for the 1970´ Lincoln´s, Mark´s or fullsized Ford´s etc. ?
This would help me getting in touch with second hand dealers.
Thank you anyway, Bill !
