New heads/intake/rear end

Probably so, never the less, it was just my opion that more cam would do it. He's looking for .30 - .40 second increase. If he gets into the heads more, depending on where there at now, he should use more cam to go along with it or there will be more head than the combo is worth.

In example;
No sense in porting the head to .650 if he is only going to use 513/.533 lift.
No sense useing a cam with .600 lift if the head stalls @ .500


Mike, can you clear this up for me? Is this correct? Am I close to this being correct?

You did have the split Crane in there and it was swapped out for the lunati 292/.480?

234/242 is the current or sought after duration of the current/next cam vs the old/current cam a Lunati 292/.480?
