Motor came out, approximately 8-9 hours. No air tools were used, lots of breaks in between. Left the manifolds/y-pipe, condesor in the engine bay. Didn't take off crank hub or opti. I'm positive the second time around we could cut the time down by an hour or two.
I did not get any pictures of the tear down but cylinders 3 & 4 had spun the bearings. Mushroomed them out to almost twice the width! Crank had a solid 1/4" groove in it on the corresponding rods. All the rods were severely grooved. Salvaged the block at least... oh and the heads look like they recently were at the machine shop. All the valves/seats are in good condition. Casting came back as an LT4 block and it was a 4 bolt main. Whoever put this motor together had no business touching anything; manifold bolts were loose, bellhousing bolts were extremely tight, motor mounts on the block side were missing 2/3 of the bolts.
Buddy picked up a 4 bolt LT1 out of a corvette this morning. Getting a hot cam/springs/retainers, timing chain new gaskets, oil pump, water pump and hopefully a converter.
