Can you upload a much higher resolution? 250kb file is too small to do anything with.

It looks like a lost cause though... maybe a 5 on the right?

I will try to give you a general idea of identifying the block markings.
1) The date wheel & flat serial number boss
2) The date wheel & stepped boss
3) The date wheel marking is retained with whatever date code it last had in the mold, but the new date code below the distributor and the steeped boss are used.
4) The date wheel no longer appears on the block and the date code beneath the distributor and the stepped boss are used.

Yours may be a replacement block (GENTLY remove any paint from LF corner of machined surface where manifolds are attached for a number ending in "X" and sometimes the "Crossed Cannons" stamp).

I believe that #2 in which it seems your block may still date from, was during the latter part of 1942 and did not happen for very long.

However, you need verification from Tom of course on this....check his FB site if you are on that platform and I hear he might get a website dusted off after he attends to personal business this month or so.

Good Luck

270K or so is all you can upload to this site.

Chuck,, it is the number 2 so later part of 42. Is there a timeline in print anyplace on the Wilson engines or do we need to piece info together from numerous posts? I havent taken the water pump off yet, Any idea of date when the 2nd hole went away under the pump, if it ever did? Just havent seen enough ford blocks to learn much about them. I think i have one of the Ford GPW books that jsut came out in print, Too many books though and no time to read them. this engine was in a gen set that was pretty much cobbled together,

Date code from far back, F 2 1 ???
