What seems SOOO simple now, was really complicated for me. For the longest i've been total timing my motor only, and could get 38* all in at 2400 after the curve kit, much more than that had starting problems. Mallory ignitions come with 24* supposedly which would put my initial at 14*, and i really need 18* from what you guys have told me. After the light bulb finally lit in my brain, i tear the distributor apart again, and it actually had about 27* in it, which put my initial at about 10-11*. Set mechanical to 20*, initial at 18*, man let me tell you what a difference it made. Could only get about 5800 rpm or so out of it before, and was bouncin that bad boy off the rev limiter at 6400 though 1st and 2nd now. I'm so pumped, THANX FELLAS !!
