Prepare barbecue (high heat). Pat beef dry with paper towels; brush with oil. Sprinkle all over with spice rub, using all of mixture (coating will be thick). Place beef on grill; sear 2 minutes on each side. Reduce heat to medium-high. Grill uncovered until instant-read thermometer inserted into thickest part of beef registers 130°F for medium-rare, moving beef to cooler part of grill as needed to prevent burning, and turning occasionally, about 40 minutes. Transfer to platter; cover loosely with foil and let rest 15 minutes. Thinly slice beef crosswise. Serve with chimichurri sauce.
