Edelbrock 7577 question
I am not sure why Edelbrock did that, but when Hughes gets their proprietary version of that Edelbrock Manifold Hughes specified different fitting locations to closely match the factory Magnum accessories, since it was intended for those Magnum truck applications. If anyone is going to fuel injection with Magnum intake manifold bolt pattern and running Magnum AC compressor bracket and location, the Hughes FI manifold is the best choice. here is a picture for heater hose and temp sensor location comparison. Note: it also makes me wonder if occasionally a regular 7577 goes out the door drilled differently.
