Hi,
I'm rebuilding a 96 4.0 with a cracked head and a blown piston. I recently picked up a set of pistons and a 7210 casting head from a parts yard, in good shape from a low mile rolled 92. I did not realize at the time that the pistons I need to replace in the 96 are aluminum. Is there any reason why this cannot be done? The bore size matches, however the rings are different (e234k, sae height) to the ones in the aluminum pistons (e925x, metric height). I do have the correct rings.
Interesting yet irrelevant: the head on the 96 and the 92 is near identical with only 2 differences. On the 92 head, the coolant temperature sensor sticks out of a threaded bung on the right rear of the head. On the 96, the coolant temperature sensor is in the thermostat housing, however the old style bung still exists and a bolt takes the place of the sensor. Also, there are 3 studs on the 96, 2 of which hold the combination manifold, and one 1 of which holds the AC compressor bracket. The 92 has no studs - instead, it has bolt holes.
