Yeah, that is the plan... Hood is the easiest one to remove....

you don't need to remove the hood.... you are not far from removing the radiator out... I just pulled mine out engine/tranny/tcase and all. I got the same HF cherry picker and was well worth it

you can disconnect the 2 hood strut rods and then open the hood higher than normal which gives the extra clearance without all the extra effort of removing the hood

I was planning to remove the engine block only, i will leave the tranny inside. So it looks easier to remove or open up more of the hood than radiator...

I also bought a 1000lb engine stand, which i plan to put the engine block on and rotate, removing the crankshaft....But I saw reviews in youtube that these stands do not really work, i.e., it can hardly rotate.

Any experience/comments?

I have a 440 in my garage (for sale, who wants it?!) on that cheap HF stand, and I can rotate it fine...

how to pull the engine block out?

I have difficulty to pull the block out....i have unbolt all bolts around the bellhouse, except the starter....do i have to remove the starter as well?

I tried jack the transmission up a bit, i preyed the engine block from the bellhouse, and can see about 1cm gap on driver side, smaller gap on passenger side(the starer is on passenger side)...but i still could not easily pull the block off...please help!!!

Yes, you have the pull the starter. The bolts that hold the starter in place thread into the engine block.

I have the HF stand as well.. it is hard to rotate but nothing terrible.. just grease it up and make sure to use the lock pin

No, they go through the bellhousing and into the block.

It might have been a good idea to pull the torque converter and flexplate before removing the crank. Since you're having the crank resurfaced they'll need to be removed.

more queston on how to remove coverter and how to mount

yes...i was trying to remove, but i don't know how...it was late last night, so i just lowered the whole thing with the flywheel sitting on a small bench, while the whole block still hanging on crane, un-bolt the bed plate from underneath(i unbolted all when it's inside the jeep, but had 4 bolts loosely holding the bed plate to actually hold the crank), then took off the crank and flywheel/torque converter all together as one piece.

Question: i now have removed the crank bed plate and crank itself, only have "half" of the block hanging on crane, how do i mount it on the engine stand? Is it from the flywheel side(rear) or from the timing chain side(front)? I assume i will assemble the engine together on the engine stand...flywheel side looks better to hook up with the stand, the stand has a 4-hole piece, i could not figure out how to bolt it on the "half" block....

Thanks a lot!

You'll need some longer bolts that are the same thread size/pitch as the bellhousing bolts from the transmission. The four arms on your engine stand can be positioned to match the bolt pattern on back of the block. Your longer bolts will go through the back of the four arms and into the block, then you can remove the chain holding it to the hoist.

To remove the torque converter, there should be four bolts holding it to the flex plate, then six or so bolts that hold the flex plate to the back of the crankshaft.
