Hello all, I am new here so this post may not be quite up to speed. I have been reading Jay Brown's intake comparo book with great interest. In regard to the sidewinder intake fuel distribution problem; in 1967 I put one of these manifolds on my 390 mustang. At the time the word was that the carb. offset to the left was done to equalize fuel mixture on the NASCAR tracks where centrifugal force from turning left caused the right hand cylinders to run rich. I figure I might be just old enough that maybe others never heard this theory. Any comments?
