Where do I get a good Torque Wrench?
For lug nuts 1/2-inch 15-150 lb. ft. will work well. That will also work on some engine parts – main bearing caps, and many/most rod bolts, and the like.
For exhaust and intake manifolds, water pumps and the like 3/8-inch 10-100 ft lbs.
For valve covers and trans pans 1/4-inch 40-200 in. lbs
If all those sizes are not in your current budget, consider what you will use the most and get them as you need them.
