How would you build a 416 Stroker 340?

just another word of advice on selecting a cam for this engine. as a rule of thumb you should add 6 - 8 degrees of duration to a cam that would work well with a hi-po non-stroked set-up. if you are porting your heads you might want to take them somewhere and have them run on a flow bench so you can get the numbers to match up cam with the correct lift to work in harmony with where they flow the most air.
