Where to get the longer crank bolt for pully install? I'm finishing up my cam install and read in the instructions you need a longer crank pully to reinstall the pully. 
Where can I get one?

a longer bolt isn't necessary. I've done 2 installs using the regular length bolts. All you have to do is set the pully on the crank, and then lightly tap the pulley onto the crank until the threads on the bolt will thread. Then you just tighten the bolt to pull the pulley on the rest of the way. Having a longer bolt would just mean you don't have to tap the pulley on so far before the bolt will thread.
Pulling the pulley off is where the longer bolt would be come a HUGE help b/c you wouldn't have to readjust the pulley puller time and time again until you could get it off.

"The bolt you need is a 16mm / 2.0 thread pitch and 120mm in length (the head of this bolt is 24mm). This bolt can be purchased from NAPA as P/N 2801-225. Price is $5.39."

I didn't use a longer bolt for my install. I got my little propane torch and heated up the center of the pulley for about 3-4 minutes, got the wife's oven mits 
and slid the pulley onto the crank snout. It went on like butter about 80% of the way. Then just used the old crank bolt to get the last 20% and stretch the new bolt in. Took all of 10 minutes to do it.

We have their catalog at work. I'll try them tomorrow. This bolt is the only thing holding me up.

The part of the pulley that heat is applied to is a solid piece, so no problems there. I've done two pullies this way, one about 6mo ago and one a year ago. Both see pretty "spirited" driving and haven't had any problems. To each his own I guess.

- I ordered a piece of 16 x 2.0 threaded rod from ENCO .
- Bought a bunch of washers and two nuts from Home Depot
- Cut the rod to about 18'' and put the washers and nuts on the rod
- Put the pulley on and screwed the rod into the crank
- Then turned the bottom nut until the pulley was seated.
This is a lot easier and puts a lot less stress on the threads of the crank. I also lubed the nut with some oil too.

Go to Harbor Freight and buy a coil spring compressor. You will get 2 of the correct sized bolts with it. Then, change your springs too 
I couldn't get a bolt anywhere, luckly I had one of these in my garage.
