I've got 2 cam shafts. 1 from a 69 and the other from a 70 TR6. Tried to find info on any differences but limited resources. Anyway I am planning to send these out for inspection/repairs and keep the original grind on one and a performance grind on the other. Haven't decided which one to use in my 69 rebuild but just want a mild upgrade in HP. Thoughts are using the original cam with an increase in rocker ratio using a roller rocker with 155:1 along with 9:1 compression, a mild port polish and port matching. Hoping to get 115 to 120 HP. Could switch and use the performance grind too which is going to be the sport 250 grind from Delta Camshaft. If not I'll save it for future back up if needed for the 6 or my TR250 witch already has the 250 sport in it.
