When you say out of the box i guess you're talking about the heads?I thought for the flow numbers that they said got that it would have made more power than they made.They were going to try a tunnel ram with 2 carbs but ran out of time or something.

Later Mark.

NO ... it hasn't got to do with porting the heads or not. IF the flow numbers you gave are real, by "out of the box" I mean simply putting it all together and running it as is, with a best guess and no further tuning.
