Re: Stroker intake manifold RPM change-PSIG???
You need to check port opening location in Edelbrock intakes from the VRJr on up as the port location in the vertical plane might not match up. The Jr sits about .05 inch higher top to bottom comapaired to factory location. Supper migh be raised more.
What yor heads flow and what lift cam you have determines intake needed as well a cubes. Your intended usage is important also.
