I’m starting a rebuild on the engine from my 1940 Ford ForDor Deluxe. It was my grandfather’s daily driver up until he passed in 1967, when I inherited it. I’m doing a partial restoration, trying to keep it as original as possible. I have a machine shop lined up for what might be needed along those lines, but will be doing all the fun disassembly and reassembly work myself. I have rebuilt several overhead valve engines with conventional cast iron cylinder bores, but never a fiat head with sleeved cylinders. The flathead issue is no problem, but I need some guidance on the sleeve issue. I can purchase replacement sleeves at a reasonable price, so I’m leaning towards removing the old ones and inserting the new. It’s a 221 cu. in.. 24 stud, 1941 vintage block engine. How about some words of wisdom from you wizards out there. Thanks in advance.

I have everything to do the .0835 conversion, but as previously stated, you have to be careful when removing the steel sleeves. I would also like to know if you find anyone with steel sleeves. A friend of mine needs some of them.
Also, you can overbore that engine to 3 3/16 (3.1875) std which makes a really good engine. You may consider having the cylinder walls checked for wall thickness if you do this. I believe I have a set of pistons, rings and pins as well (still in cosmolene).

What he said! I'd probably have it bored/honed to the next available piston size (depending on whose pistons you're using).
