106 for that combo.


Hoping you have ported the street dominiator to at least nearly match the flow potential of your heads....or it will cost you a good bit at the top of the RPM range. A well ported SD from my experience can flow about 310-315 vs ~270 stock. Well ported it's a great match because a shorter runner (compared to say a Victor) is less restrictive for a given flow, longer runners are better for torque but that's not an issue for a 4.15 stroke.
