I have the petro works in mine with the first generation motor mounts, they are the soft ones that I like alot, not sure what they have for that now, the mounts move the engine and trans down and the engine to the passinger side about an inch or so for headder clearence, been running it for about four years with a 16 valve and only went though one rubber mount in the front that I changed myself for like twenty bucks and a 100 ton press LOL,the trail tough is good also but you need to put a small body lift in the front only about the thickness of your finger.
