I have a Farmall 400 engine block that I want to bore to accept 4 3/8" pistons. Without sleeves, I think the bore is 4 1/4" (I may be wrong there). I am wondering if the structural integrity of the block would be stronger if I simply bored the sleeveless block to accept the 4 3/8" pistons and then hard blocked it(without sleeves). Or if I bore and sleeve the block for the 4 3/8" pistons and then hard block it? It will be running 5.75" stroker crank under 2000 rpm @ 200 PSI cyl. press.
Thanks alot

Been there and done that on the sleeves Kenny. To run a 4 3/8 sleeve you'll have to bore that block about 4.5. I tried it and it weakened the block so much it cracked in about 4 places. All you need to do with your 400 block is bore it .125 to get 4 3/8. That's only taking about .062 of metal off each side. If I were going to use any hardblock I'd only fill the block halfway as LW and Casepower are doing on the "Project M" article, and pour it before you bore. It could shift your cyl walls some. That 400 block has 4.5 inch counter bores also. Either weld them up or make up some press fit inserts for them before you bore the block so the stock head gasket can still be used. Check out the article in OPP. Lot's of good information.

The problem you will have if you bore it out and then sleeve it, is water leaking into the engine. Before I done anything, I would remove the sleeves and have the block sonic checked by someone that knows what they are doing. We went 4-3/8" on a 356980 C-281 block and the thinnest part after boring was .120, but still hard blocked half way up. I wouldn"t listen to any advice on your block, I would have it checked. But if I had a choice, I would not sleeve it. Unless you plan to have the sleeves professionally brazed in, you will loose block strength.
