460 Posted April 29, 2020 Share Posted April 29, 2020 link to archived topic Ok so my old topic was archived. I figured I would start another to show my latest task. A 263 punched out to 291cid. So this is where I am at at this point tractor is split. Awaiting on parts from machine shop. Short block is assembled. This is not your normal 291, it has no Reliance parts. It has custom built pistons with modern .062, .062 and 3mm oil rings. NOS crank and rod bearings. Compression is right at 9:1, I have thermo coatings on the chambers, piston tops and exhaust ports. It has extreme duty valve in the head (Stainless) with good quality seats and broze valve stem bushings. Cam is a Vogul regrind. 5 Quote Link to comment Share on other sites More sharing options...
460 Posted April 29, 2020 Author Share Posted April 29, 2020 I will post some of my engine pictures later. This will be dynoed for break in and tuning purposes. Of course this will also be telling me how much improvement I have made. My goal is 90hp with the stock 656 carb @ 1800rpm and 100 plus on torque rise!

460 Posted April 29, 2020 Author Share Posted April 29, 2020 Here are some of the pictures so far of the build! Note the difference on the stock replacement piston in comparison to mine I took 200g out of each piston. 4 Quote Link to comment Share on other sites More sharing options...
nepoweshiekfarmalls Posted April 29, 2020 Share Posted April 29, 2020 Looks great! Should run well. Dad had a 291 powered 706 that dynoed 70 HP. 1 Quote Link to comment Share on other sites More sharing options...
460 Posted April 29, 2020 Author Share Posted April 29, 2020 Thanks! The old 263 made 70hp with the lp intake and carb set to rich at 540pto. I had that setting for the fair pulling and under normal field conditions I leaned it back a bit which put at right around 65hp with a significantly less fuel. This 263 is tight but will need a head soon as it has a sticking exhaust valve. I estimate it has less then 400 hrs since the major. It was redone in 1998 before I bought it. The old engine is going into a neighbors 656. Scott Quote Link to comment Share on other sites More sharing options...
88power Posted May 8, 2020 Share Posted May 8, 2020 Very nice it's been a long time since I've seen one of these apart. Is this just a puller or you gonna use it? 1 Quote Link to comment Share on other sites More sharing options...
460 Posted May 8, 2020 Author Share Posted May 8, 2020 I use it, I have 5 acres that I till for soy beans. It also get snow blade duty in the winter, when we get enough snow. 2 Quote Link to comment Share on other sites More sharing options...

460 Posted May 24, 2020 Author Share Posted May 24, 2020 Finally made some progress today, cam is in final time degreed with the donor motor gear timing set. Had some delays as I traded my running 263 for a non running 263 and it took me a bit to get through this poor 263. I was able to salvage everything I needed off it plus a good crank and head, but 5 had about 1.5" of rust. I also helped my dad upgrade his brakes on his cobra, took a bit extra as he had a twisted axle and we had to upgrade the master cylinder to a bigger bore one based on my calculations. 5 Quote Link to comment Share on other sites More sharing options...

Its a Northeast classic kit car. It is powered by a 351 windsor with a auto. Dad would like to put a stick in it but we will see. 1 Quote Link to comment Share on other sites More sharing options...
460 Posted May 30, 2020 Author Share Posted May 30, 2020 Finished the head assembly and install today. Used ARP studs and silver paint method with a NOS Felpro gasket. We have a whole collection of rockers from over the years. Note the design changes. Dad said some of the pullers that use stock rockers are after the early style for strength. I choose the middle with the nice's shafts I could find and flipped the wear side of the shaft to the top. I will be call Smith Brother Pushrods on Monday to order a set of slightly stiffer push rods. Getting closer! Scott 3 Quote Link to comment Share on other sites More sharing options...

460 Posted June 28, 2020 Author Share Posted June 28, 2020 Finally getting back to this thing today, after 2 weeks ago breaking water temperature fitting, there brittle. It was great fun drilling it out and tapping it upside-down so shavings don't go down the clean water jacket. Governor went back together with a new seal and I added a washer to the one linkage to tighten it up with some fresh grease too. I went alittle OCD on the side cover and aligned all the screw heads. I just have the oil pump to clean and build. The water pump will need alittle clearancing at the top as it hits the head (effect of milling alot off the head and alittle off the block). 3 Quote Link to comment Share on other sites More sharing options...
460 Posted August 31, 2020 Author Share Posted August 31, 2020 Finally was able to dedicate a day back to this engine! Finished assembly of the oil pump and oil pan, I prime it upside down with the gear off then remove the pump and put the gear on after priming. This ensures no chance of dry start. Anyway oil pan is on finally. Dad is going to throw some primer and paint on it this week and maybe I can slip it in the chassis next weekend. 6 Quote Link to comment Share on other sites More sharing options...

MinnesotaFarmall Posted September 20, 2020 Share Posted September 20, 2020 So, I'm a little confused unless I'm missing something, but isn't that a 666/686 front assembly? Title says 656... Quote Link to comment Share on other sites More sharing options...
460 Posted September 20, 2020 Author Share Posted September 20, 2020 Yes sir! I put a 666/686 front casting on a 656. Seen it done a puller years ago, and liked the light setup just like the big tractors. This was covered in the archived thread linked in the first post.

460 Posted September 21, 2020 Author Share Posted September 21, 2020 Getting closer...did a muratic acid flush on the Radiator a couple weeks back well it still did not clean all the calcium deposits. So did another flush today. Well apparently the acid even though I did a though flush ate through some tubes. So its now junk! I am just going to buy a aluminum one and hopefully be done! Should have done that in the first place! I chose to use Evaporust on the inside the fuel tank as it had just a tiny bit especially in that bulge areas that is lower then the fuel line. Did a flush with diesel then gasoline. Its back on and ready for next weekend! 3 Quote Link to comment Share on other sites More sharing options...
MinnesotaFarmall Posted September 25, 2020 Share Posted September 25, 2020 I haven't heard much good when it comes to alum rads. Our rad guy says they crack, and it's twice as hard to fix them. Quote Link to comment Share on other sites More sharing options...

I will rinse the old one and store it assuming the tanks are still salvageable. 4 Quote Link to comment Share on other sites More sharing options...

Not sure that any one is any more, I believethis came from Hycapacity. I can get you the thickness if you want to make your own. Quote Link to comment Share on other sites More sharing options...
