I have a 1968 G900 diesel that I bought for a bargain price. After running it some, I heard a slight miss and and occasional knock. I tore it down and it turned out to be a broken piston land and ring. It scored the block. I overhauled it by having the blocks bored out to G1000 standard size (504), with new pistons, valve job, etc. It now starts really great and sounds sweet. I understand this combination raises the compression ratio to around 17-1. I used it on a 15 foot brushhog, which it handled just fine, but I"m looking to replace the mower with a 20 footer. Would this be too much for a 504 inch G900? The G1000 is 110 HP, and this tractor is now a couple of points higher compression than a stock G1000, so would the power also be over 110HP? The governor was set up when I got it and it holds 2000 RPM under load.
