The newest "building a slant six" thread

You are going to get a lot of opinions but the things mentioned in posts 7 & 8 are good basic things to do. Both of these guys have many years of /6 racing and driving experience.

There was a slant 6 dyno article in Hot Rod mag a few years ago. Number one power adder was a bigger carb. Your Weber is right on.

Opening/enlarging the exhaust is also very good. You will feel the timing changes that John mentions in #7.

Is there even a single machine shop on your island? Milling the head. 080-.100 is a good thing. Charrlie told me about 5 yrs ago there is no downside.

Once you get your basic plan, consider contacting Oregon Cam for recommendations. They can regrind your stock cam. (lift in 1968 was .395)
