Hey guys, I'm helping a friend build a injected, stroked 5.0. He has a Performance Products Typhoon intake manifold. This is going to be mated to a set of Trick Flow heads. The difference in the size of the intake runners to the head runners is substancial. Is this common on Fords/injected vechiles? I am GM/carb guy. I am planning to increase the intake runners to match the heads, leaving a small barrier on the intake side. Also what about polishing the intake since there is no fuel mixture until the combustion chamber.
Thanks for any info you can provide.
