Most automotive machine shops do not have the proper equipment to bore a TR6 block for cam bearings. Bring us your block or have it shipped to us and we will bore it for cam bearings using our own dedicated equipment designed specifically for the job. Price does not include cam bearings, installation of bearings or return shipping. Bare blocks (main bearing caps are not needed) can be shipped via UPS. The block should be bolted into a plywood box with cardboard covering the outside. The total weight may not exceed 150 lbs. Good Parts can send you a shipping box and return shipping label.
