I am installing a 2004 5.3 out of an avalanche into my 1965 c10 and have the engine in place and the engine mounts loosely bolted. The engine seems to want to sag down in the rear quite a bit so i have it tied off for now. Do i need the transmission installed and transmission crossmember installed for proper alignment or if I tighten the engine mounting bolts down will the engine not sag real bad. Sorry for such a simple question but this is all new to me.
