I have my 5.3 mounted with the 6 cyl stands. I mounted them in the back holes on the frame. Used the 68 V8 engine rubber mounts mounted to adapter plates made frome internet pattern. The engine sits back good. Used 4l60e from 2005 silveado. The tranny crossmember had to be moved forward about 2 inches maybe. I used Doug Thorley headers that dumped pretty close to the tranny crossmember, so had to use 2 ich exhaust with pretty tight ninety degree bend to clear. Also required Lokar cable shifter to use column shifter. Headers blocked mechanical linkage. Get the longer cable if you go this route. Not as tight bends. Good luck. Jim
