I was favoring the 400 over the 350 or 383 because everyone has a 350 and it made a little more power. What are the disadvantages of siamesed bores?
Pump gas, 10:1 max.

The siamese bores tend to be a lot harder to work with, with the water jackets where they are and stuff, 350 is a lot easier to work with, specially if your a beginner. Personally, I'd make an 8:1 motor and mount a 6-71 or 8-71 Blower on it, I'd be a runner for shure.
