There are all sorts of techniques for finding Top Dead Center on #1 cylinder. Use Google to find the one you like best. Once you have your engine at TDC on #1, you can put a temporary or permanent mark on the pulley that covers the balancer. You can put the mark anywhere you like as long as there is a corresponding stationary item nearby that you can use as a pointer. Or you can fabricate a pointer and put it wherever you like. Once you have TDC marked on your pulley, you can put additional marks for 10 degrees BTDC or whatever you like on the pulley. Just measure the total circumference of the pulley and divide that by 360 to find the distance per degree. For example, if the pulley were 36 inches in circumference, each tenth of an inch would be one degree. Assuming your pulley turns clockwise (when looking from in front of the car), a mark one inch clockwise around the circumference of the pulley from your TDC mark would be 10 degrees BTDC.
