This particular engine, will be on the track. A this time, it is only a guess on the compression ratio, but thinking of the cyl pressure to be 200-210 psi. Roughly,, 10:1-10.5:1 compression ratio. I am going to feed it 94 octane pump gas. Most LP IH engines were around 200 psi of compression, but have you ever seen those pistons? Very high domes on them. And if there is still some new on the shelves somewhere, they are still very expencive. I know in our area, we used 806 LP pistons in our H pullers,, and the company that sold them to me, said we bought the last set available! Dont know bout the availability for the 263 LP pistons as far as new pistons are concerned. In my honest opinion, this would run in the fields all day long, provided the carb is set up to the added compression to compensate for the power increase. If not it would lean out, and burn up the head, gasket, or the piston. I am hoping, if I do get 200+psi of compression, I belive that the 263 would make 90+ hp, on 94 octane fuel, at stock rpm, and live to tell about it. And use IH stock bore pistons to do it, even though it takes a bit of machine work to do so. As far as the cranks being able to hold the HP, the diesils, are almost the same crank, if the tolereances are in good order on the thrust, and the rods and mains, it will hold up, that just my opinion,, ChadS
