Since I have decided to go stage 2 I no longer need this intake. The intake will require you to change the throttle cable to a universal one or one from a tpi iroc, you will have to make some brackets for the 2004r transmission also. Yes it fits under the stock hood, and best fits gn-1 heads ports are ported to felpro 1200 intake gaskets. I have reduced the price to $1200, but i am open to offers. I will include the ford 75MM TB with Tps. It has no thermostat, but I will include a thermostat that goes inline for free.
