I just completed a bunch of work on my 260. Rebuilt cylinder head, timing chain, gear, headers etc. In any case I don’t know if the oil pump has ever been changed, I saw a high capacity oil pump on the motorsports website. They of course have the standard one as well. The high capacity one claims a 10 to 15 % increase in volume. Would this be beneficial in a basically stock engine, could it be harmful, or it just doesn’t matter Anyone?
