IH 266 c.i. SV V8 IH built a 266 c.i. version of it's popular SV V8 engines. Like the 345 and 392, the 266 was way over built for light truck use. High nickle block, extremely well balanced, heavy duty deep skirted pistons, etc. My first car was a '67 Scout with a 266. Great little motor that pulled that old Scout through any snow, mud, rocks, dirt that Northern Minnesota could throw at it. One year at the local county fair, my brother decided to enter a late 70's LTD in the demo derby. We decided to use the Scout as a tow rig since it had been a rather wet summer and rumor had it that tractors and Bobcats were going to get swallowed up in the red iron clay / soup. By the end of the night, the Scout was the only tow rig left that wasn't stuck in the mud. Light weight, 35" Mudders, with locking diffs front and back, and I was having the time of my life dragging anything and everything out of the muck with that little 266 singing away through 2.25" duals and a pair of Cherry Bombs.
