On my '07 Tahoe It took me 5 days working anywhere from 3-6 hours per day. I ran into a few problems along the way, nothing major but I spent the better part of a day chasing down an oversized balancer bolt since my installer was too short. I was also missing 1 arp washer and one was unusable because it had no chamfer.
I'm pretty **** so I spent longer then most making sure deck surfaces/bolt holes were perfect, and degreasing stuff that was unaccessible before. I didn't want any problems as this is my family vehicle.
To the OP, my advice would be to set aside a few days just in case, and don't try to do it in a set amount of time just to say you did. Take your time and enjoy the experience!

Yep, I'd say I worked about 20 hours total give or take. Its hard to find time when you have three kids that need constant attention. When I go in the garage to work on something I usually lag it out on purpose to have some time to myself.

im on 120000 on this chain
dowel rods to hold up lifters. air hose from a compression test kit to hold up the lifters. Undo the front of the pan to unbolt the pickup tube and remove the oil pump. Pick up an LSx balancer install tool from Sdparts.com to put the balancer back on unless you don't mind risking messing up the crank or bolt threads. happens some times.
Seems to take forever to do the springs one at a time. Just clear a day. I think the first time I did one was around 7 hours cuz we had to find a 3 jaw puller for the balancer. that was just cam and springs. creeping on 200k miles now and still have stock chain and pump.

cam swap on a 99-07 . . . 4-6hrs, from drive in to drive out
cam swap, DOD delete, timing chain dampener swap (dropping the oil) pan 10-12hrs
a timing chain on a 99-07 at 120K miles is just as loose as it is when it's new . . .
Now a timing chain on a 07+ can be pretty sloppy if it's the stock "black" chain

10-12 hours if you take your time. Just use the dowel rods to block the lifters. It takes 10 seconds compared to screwing the fitting into each spark plug hole one at a time. And warm the balancer in your oven, and it will slip right on with no special tools.

Map gas on crank pulley
any thoughts

Heat evenly or not at all. MAP gas torches will spot heat the balancer and potentially damage it. The pulley is already sort of brittle and stressing it with uneven heat then putting it on the crankshaft might not work out so well. I'd recommend just setting it on the crank and using a 2x4 and a maul to tap it on until you can use the old bolt.
