International Farmall 560 budget build C301 to 376 cubic inch stroker. 9 to 1 compression on pump gas 90 octane, stock rockers & head, low idle timing at 10 degrees all in at 30. After a few jet upsizes on the 63aw12 carb it’s pulling at a safe a/f around 12.5, pto clutches won’t hold much over 100+ hp on the old M&W p-350 @ 540. No load rpm set at 2170 for div2 10% over. Tested at 1800rpm and lots more up higher.

1974 Case 1070 8 speed in for a tune up for the county fair. 5,000 original hrs with stock pump settings for the initial dyno numbers. Was right at the limit for the 540 side. I’ll probably switch the pto to 1000 after the valves and pump get adjusted just to be safe.

Spins nice and smooth like it should. C301 International Farmall 376 cubic inch stroker. Got lucky and the camshaft was only 1/2 degree off dot to dot.
