Ok this day sucked. Figure on a an hour or two to set my engine in, well turned into an all day affair. Its a 454 big block, but since its going in a small block truck, i was told to use the small block clam shells and inserts, so i bought energy suspension 4 bolt style inserts pn #3.1116 whereas my donor vehicle had the 3 bolt style.........WELLLLLLLLLLLLLLLL fast forward to today. When you drop the engine down it hits on the tabs that stick out of the insert. So i ground them down a bit...After taking them on and off 3 times for just a bit more grinding, had em where it shoulda worked. Well till when i put the weight on it snapped off the tabs....argh... well ok, i dont need the upper tabs lets see if it lines up. Well its dark, cant see nothing, bolt wont go through and had to tell if the holes in the insert are closer to middle of truck that the ones on the outter holder that attaches to the block, or whether the bottom tabs is keepin it from lining up. Now the question...How much are them little tabs needed? Im at a loss, thing wont line up at all. What shoulda been the easiest part took a whole day and still nothin got done. Sorry for this being so long.
