4.6 engine with a forged built bottom end fresh out the machine shop with ARP head studs ready for boost. Edelbrock Intake has fuel rails and injectors right along with an extra Edelbrock elbow with a throttle body. Have a spare pair of heads in good condition just needs to be sent to the machine shop cleaned up with new valves, also I have a new set of trickflow & melling lifters brand new in the box.
