My "56 Dodge Royal Hardtop with a 315 Poly ran well and I never thought about doing a tune up until recently. I installed a Dizzy which I had converted to Pertronics and proceeded to set the timing. Well, to my surprise, NO Timing Pointer. Why, I do not know! I looked all over to find a pointer with no avail until my friend Dave F. put me on to Scott T.. Scott sent me a bunch on photos and from there I proceeded to fabricate and pointer. New pointer installed and setting TDC with a Piston Stop and marking the pulley, wallah, the old beast runs like a dream.
