4.0 exhaust on 4.2 head?
« on: April 06, 2012, 02:28:09 PM »
i have the short header fr the 4.0 7120 head sitting around waiting for the engine build and an exhaust currently in use that needs attention. does the 4.0 header fit the 4.2 head? i have no issues fabricating the rest of it as long as it fits the head. i also have another 4.2 to test fit on but i'd rather not go through the trouble if anyone else knows or has ideas. thanks

it bolts on but you have to modify it cause it will get in the way of the front axle

1981 Eagle Kammback (restoration in progress)
