Specifications:
Who actually makes these? I am looking for a manifold that has ports in the correct location, not a product from a place that doesn't have QC. Thanks.
Does this intake fit under the hood of a 1977 Corvette with vortec heads and stock air cleaner ?
What is the torque spec and sequence? Thanks
