It is apparently for an early engine with a 1/4" dia drive for the oil pump and the smaller dia bore hole in the block.
The later 170, plus the 200 & 250 have a larger dia bore hole in the block and use the distributor with a 5/16" dia oil pump drive as you stated and as it says in the Falcon Handbook.
Yep, based on the fact he replied "1/4inch" to me as well, I'd agree with Darrell's conclusion; the 1/2inch is a typo, and it's a 144 early 170...wierd thing is he made the same typo (1/2 inch) when he updated the info on the load-o-matic that he is also selling.
The one that was originally in the 170 (see article pics...at least that's how I gathered this guy is somehow connected to that project/article)
EDIT: I think it's still possible it's the larger 5/16" shaft & larger bore dizzy (seems strange that a PO would have put in an earlier engine, not that it's impossible)...I can't tell though by looking at the pics, and am also not sure of the bore size on the earlier 170's (ie just how small it is

: )

since the 170 I have (C4DE code & casting date Nov 12, '63) has the larger distributor bore hole and is machined for hydraulic lifters. Who knows???
It's definitely a puzzler, and it also seems obvious the guy is not paying that close of attention to this
"six cylinder stuff :roll: "
Kinda hard to be sure what engine it even is with the limited pics/info...I once drove 2hr+ to the 'well' north side of FW to look at a cheap '200' engine being pulled for a bent8 swap...it was a 170, asked him, "what made you think it was a 200?"...'says so on the air cleaner'

As mentioned earlier in this thread regarding the article, they just don't get it, and don't care.
Maybe another way to skin the cat (and know for sure) would be to ask for the part number on the load-o-matic dizzy.
