Ok, I guess I should have specified. The complete suspension has been swapped out with aftermarket parts to include a tubular K-member specifically for the 4.6.
In case anyone is interested, no, the motor mounts cannot be swapped. They are side specific.
'97 to '01 motor mounts are the same according to advance auto parts. (I'd check somewhere else before taking as gospel. I don't trust them. Been burned by them before)
The engine went in last night. I lowered the k-member about 6 inches, dropped the engine into the k-member mounts and then jacked the k-member/engine back into place.
I do have the 2inch of space between the engine and firewall everyone promised me.
Now, how level is the motor once permanently placed in the car? Mine tilts back a little even when the transmission is bolted in place.
Thanks everyone for the help.
