A great read for sure. Myself I grew up learning it old school in the 70's and still do not have an 02 on my 63 as I still mostly tune thw old way I learnt. But I do understand you cant beat technology and the 02 will tell you just what is going on. Course we use an 02 in my sons car since we added the Holley fuel inj. Some time down the road I should add the 02 setup to my 63 but I am very happy with how it runs now. Ron
