First disaster so far was spraying coolant all over the garage floor. ugh.

Is it anymore difficult to install the kit with the smaller pulley?

Welcome - I'm about 2/3 of the way thru this servicing too. 60k was never done by previous owner -- so I'm doing the 120k at 92k.

FYI -- Our Z engine keep on giving in terms of coolant leaking out --lots of nook and crannies in the block. I used the lid from a larger plastic storage bin as a catch basin under the car. I have the front of the car up on a few 2x8's to make servicing easier -- had to drop it back down to get rest of coolant to drain out. Stuff kept dripping for days until I did this.

Previous owner had installed an UD pulley -- came off pretty easily. Would imagine going UD vs stock in terms of installation is pretty similiar.

i remember seeing that the timing needs special adjustment with the smaller underdrive pulley, is this correct?

Nope -- everything works the same way. Only issue I've seen is some folks over on tt.net have posted that noname UD's listed on eBay may not have timing marks.

I have an Unorthadox Racing UD -- checked timing before I began the servicing and it was right on as 15 BTDC, very easy to read the marking too.

Once I had both the coolant pipes off I siphoned out a bunch of coolant using a plastic hose. That helped keep the amount that came out when I removed the water pump to a minimum.

I know that there are two drain plug/bolts to drain the block, but I decided I'd rather not break the factory seals on those.
