Set me straight...
Tried my best to degree in cam tonite... Can't make sense of the info I got
To start, installed the cam gears dot to dot, as in cam dot on bottom, crank dot on top, make sense so far? This results in TDC on compression stroke, cam dot up, crank dot up? Right? I hope so..
Locate TDC w/piston stop. Reset wheel to 0. Rotate clockwise from front of engine. Cam card states intake opens @ 9.5* btdc, which I believe is @ 0.050. My findings were 9*, good so far? Where does the 4*adv come into play @?
Cam card says intake centreline is 106. I got 105, again, not sure how to apply advance?
And intake closing point.... Is where the wheels come off, or not, I dunno... Cam card says 41.5* abdc I cam up with 53... What happened??
Seat to seat... This is a mess to... Intake opens 34*btdc and closes 100* abdc
To recap, I'm lost, need advise, again. 0.050 duration is231/239. Advertised is 282/290 Lunati20120712
Where does this put me in terms of DCR now?
I spun this engine over about 40 times tonite, pretty consistent on data, but I can't interpret it

When the dots on the gears at dot to dot #6 is at TDC on the compression stroke. For #1, the dots are both at 12:00. Could make a little difference if you're checking at #1 cylinder.

I went home today, put basepan, timing cover, damper all buttoned up... Cleaning up tool, cam locking plate on the bench - forgot to tork in cam. Tear it down and redo it all. I swear I've redone every bolt on this engine 3-4 times! I suck.... But it's close now!

The crane failed because part of it is missing. There should be support bars from the top of the vertical bar down to the back horizontal bar. There is no way you could expect that to lift any weight the way it is.
After looking at the pictures again, I see the support bars laying on the floor beside the crane.

It's just an oil pan, looks like it should have been a slow drop.
I've seen a very expensive 540 bite the garage floor when the idiot that tried to use a tricycle engine stand and hit a pebble on the shop floor about the size of a pea. Cost that guy a pan, valve cover and tear-down.
Add the straps (the ones laying on the floor) and it will work fine after you get the base straightened out. I've lifted way more with no issues on any of the shop cranes I have.

Thanks bashcraft, that's exact what the wife said 
Those straps were about 2" to short to use in any of the holes...
Bought this thing off a buy/sell website locally, used. Now that I have my hindsight clearly focused... Thinking it was already leaning forward. Never used one before, so wasn't sure. Just kept going.... And u see the result
I took the weight of the engine, and went to loosen the bolts... But as soon as they were lose, it shifted, first thought was the jack is creeping down, gave it a few pumps... Haha and I actually watched the ram for a second - didn't step back and look at all of it. Not creeping, pulled the bolts... Last one over 1/2 way out, and crash! Called it a night

Just leave everything loose until you get all the bolts on the lift started. Then just crank it back into place. You just bent the flange a little. Make sure you check the pan and if it dented, I would pull it. Just to make sure the oil pick up didn't get shifted or worse, pop off!
