Holley Strip Dominator
Well, it is a race oriented intake. So be prepared for cruddy low rpm driving. If your going to have a decent cam in there with your 3.91’s, your going to need a decent stall converter to go with it like Fisher was saying.
You didn’t mention what cam you want to run or the engine displacement.
The MP - M1 is an upgraded version of that intake with a spreadbore carb pad for the TQ. I’ve run that.
