lynn,

again, what advantage is there for u to use a tunnelport head that nobody uses instead of a rectangular port that everybody uses??

Cross Sectional area to eliminate CHOKE. A major factor in achieving HP in higher cubic inch engines. I have posted the approximate calculation several times.

and how will ur tunnelport head compare to the dci head that they said will flow 475??

Bob's heads look very promising. I am in no way trying to infringe on his success. I will support him 100%.

We are looking into areas where an inline cylinder head has scientific restrictions.

Remember that flow doesnt always mean horsepower. There are several areas of flow in a cylinder head that actually reduce HP.

At 475cfm, then it should produce 1140 horsepower with the proper componets. I hope he is successful. Like I said, I will be one of his biggest supporters.

i suppose question 1 would answer question two. sorry. <HR></BLOCKQUOTE>
