I've been on here a little over 20 months and have never X any one.
I have built a few 2.2's, 3 273's, maybe 15 318's and 20 360's but never a 340, never need to. I am doing my first 5.9. I've helped build many others. I started when I was 12 and I am 65 now.
I tend to get IGNORANT when someone calls me stupid or fool. I have studied most things automotive over the years, and I have a lot of hands on, not just book learning. I also try to teach or mentor people if they want to learn. But if you think my answers are Bat Crap, explain in simple terms and I may learn.
