Re: 400/406 Builds
I agree with going with a different cam, especially in a 4x4 with 3.42 gears. What size tires will you be running? You need an engine that produces low to mid range power, with emphasis on low range, not mid to top end power. That single plane intake is not the best for low end power either. A dual plane would be preferable. Did you read post #1 of this thread where I described the 400 we built for my son's 4x4?
