I am trying to get clarification. Understand the true FT blocks have a compressor drain back to the block. Is that how the blocks are identified that need the distributor? It wasn't measured previously to assembly.
-
My D4TE block has the compressor drain hole on the passenger side skirt, but has the 'automotive' size hole for the bottom of the distributor. I was expecting to need a bushing, so I was surprised by this.
-
It's confusing and I should have taken the precaution and measured. I understood it was only blocks used with dump trucks and such.
-
Mostly 331, 361, 391 truck blocks but there are several others. I'm just naming the most popular .. ::) give me a break guys lol..
-
I just took my D4TE block down to the machine shop last Saturday, and just before leaving I did a quick and dirty measurement of the distributor hole using drill bits to check the ID. Seemed to me it was an easy fit for a 7/16” shaft. Can anyone tell me if that’s the large or small hole? My rebuilder block didn’t come with a distributor.

Sorry for being such a newb, but still looking for an answer to this.

A 7/16 bolt is a loose fit, 1/2 is a no go on a passenger block

So, is the 7/16" hole a "passenger" distributor hole, and a 1/2" a truck/HD sized hole? Thanks for checking, but not having more than one block lying around, I can't compare one to another. I think I'll get hold of POP to maybe clear this up.

Rider, a29/64 drill bit is a nice fit (.448)
A used fe distributor is (.450)
Hope this helps you.

The bushing Ford used to service to adapt the FT block for a FE sized distributor is part number C4TZ-12367-A. I measured the O.D. of an NOS bushing and it is .518”

Yes 7/16 + is passenger

I made this a while back when this question was coming up frequently on my FB FE group.

Interesting, as there's no doubt of the D4TE casting. The date code is a little muddled, pretty sure it's January '76. So, looks like a passenger-type dizzy.
So easy to get misinformation, I emailed Precision Oil Pumps who makes a repop bushing. They assured me that it's a truck block and I'd need the bushing.
Thanks for all the help, everyone!

I think you are confusing the car vs truck aspect of this when you say "passenger" block. D4TE blocks where mostly (95+%) used in light trucks (F150-F350s). These engines all used the regular FE distributor and therefore have the smaller hole. The only engines that used a different distributor with the larger shaft (bigger holes) were the medium and heavy duty truck (and some U-haul light truck) FT engines.
