Anyone one know how to build a 44-6 to get the most possible out of it? Stroke, bore, pistons, rods, cam?

First try to find a 244 or 245 block with the same configuration as your 226 or a complete engine of 244/245 cu.in. Maybe a hyster fork lift engine maybe or a power unit. Clark Lift trucks won't work! The 226 block that Massey used was the most common block,(bypass oil filtering, standard 6 stud flywheel flange etc.) Bore out the 244/245 block .060 and that gets it to about 3.5" bore. then start looking for heads with different chamber volumes, maybe a head from a 209 or 218 cu.in. engine, get a head with a smaller chamber than the 226 to get the compression up a bit, don't mill it a lot, just clean it up. Thats a good start. The engines do not have a real strong torque curve at low RPMs, you have to buzz them to 2500-2800 no load gov. setting. When I was working at the plant here in Muskegon I had a stock off the line F226 on a go-power dyno over 60 hp. Continental advertised the 245's to get 75 hp with the big carb/intake combination at around 2600. Remember the gov. must be in good shape and 44-6's had the small intake bore. I could tell you a lot more but it would be a book, It would be easier to do it for you if I had time, it takes some good machine work. Don't underestimate a .060 over 226 (Your orig. 3 5/16" bore block) either. A B-427 or M-330 are both physically larger than the F-series 6 cyl. The M290/330 did get used in I think the 203 Massey wheatland tractors of the early forties. The B-427 is huge and heavy. Anyway if you are thinking about pulling with it, it wouldn't be that bad but you should have it running as best your hip pocket can afford.

First thing I would do is install an electronic(breakerless distributor) ignition.Then go to work on the carburetor.

I have had good luck with the pertronix and would plan on 1 for this. I'm really looking at a total tair down and rebuild, matching everything up to make it as hot as possible. Thanks for the reply and thoughts.

Dropping a 330 in, would bump the power, but you
are approaching a lone outpost. Few seem to follow
the flathead six path for power, they rework the
H260's.
