I have switched to a dart cast rectangular port tunnel ram with 2 1150hp holley carbs. What sort of gains would i expect with this setup? The old setup turned to 7200, where would this new setup make peak power. I would think around 7700. If the duration is a bit small on the cam i could bring the lash in from 0.030 to 0.024 to increase it.
