I noticed today that I have a block that does not have the script "Ford", and "Made In The USA" underneath the water inlet. The serial number indicates a 1924 casting. What do I have here? Where did this block come from? Any idea's?

Thank's.

Steve

Perhaps it's a '26/7 with a modified serial number. Does it have threaded bosses at the rear of the cylinder caating to mount the later style transmission cover?

Hi Steve
You wouldn't be sitting on an IPCO motor by any chance? See a thread [with photos] from back in March. They were a copy of the T engine made by the Interchangable Parts Co'y in New York. Casting details are inside the block. I can't find any others in New Zealand so far, but there appears to be one in Australia and possibly one in the Eastern States

Steve,

I have a late 25 [July]that has no script on either the block or the head and have never found any other markings on it anywhere other than a serial number stamped where it belongs.

I just assumed at somepoint in it's life it was rebuilt with Western Auto type generic aftermarket spares.

Runs good at that

My '26 Runabout ( Oct 26 ), yeah I know it should be listed as a '27, does not have the ford script engine block. The frame & engine #'s are the same.

According to Bruce Mc., during 1923 for a while, the 'Ford' and 'Made In USA' was left off an untold amount of blocks. My 1923 is missing the 'Ford' and 'Made in USA'.

Also beginning in Aug 1926 the 'Ford' script was omitted from cyl heads for the remainder of production.

Or, you could have a replacement block, not made by Ford.

My Nov 26 has Ford script but not the made in USA on the head. I'm wondering how many casting mold's were made & by what supplier, the guy on the assembly line would just grab them.

Re: the IPCO Ad what is Semi-Steel?

Alex...

Semi-Steel was a broad definition for low carbon cast iron.

How did they make low carbon cast iron? Oh, a mix of pure iron and scrapyard scrap...lol

George,

Kinda like Carbon steel knives? they hold an edge through a whole roast. Only knife Hannibal Lechter will use.

Alex

Semi-steel sounds like something that a marketing department would come up with.

Alex,

I could be cute and offer why the good place in Asia foundries are able to pour high strength cast iron that tests at 44,000PSI, where the rest of the world can only get 37,000 psi for the supposed equivalent mix of materials.

Those Asian good foundries use 75% virgin pig, 20% foundry offcast repour, and 5% 'whatever'. To their way, that 5% 'recycled whatever' is old diesel engines...complete and assembled, oil drained only. It's amazing what a 4140 or so crank and cam and a few valves can do to cast iron strength on that basis....they may work cheap, but they sure are clever!

Same I suppose as the old semi-steel of the past!

I had a block with no Ford script or anything on it that I found in a salvage yard several years ago. It was bare, not even any main caps on it, but was in very good shape. I don't know why anyone would have sold it to the yard. I traded it to a friend and he said when the shop did the machine work on it, it was somewhat harder than the T blocks that had the Ford script on them. He has had very good luck with it. Just my .02. Dave

I haven't paid much attention to it, but I don't think you will see a Ford script on a block after 1922, or a casting date either. In 1927, they didn't put Ford on the cylinder head.

According to Bruce's "Model T Ford Encyclopedia",---- "FORD USA", is no longer on engine block. September 25,1923
