Thanks for the update...

Thought maybe the coronaMIBriotdemoprotestBLDMmonster got you.
Well, after all... what would Banacek say ?... “AOC - her astonishing matryoshka-like ignorance, like the rest of The Squad is surpassed only by the relentless idiocy of the democrats, antifa & it’s attendant mass media, mayors & governors.”

After some research and checking, I ordered a Cloyes C3211 timing chain. It's twice the size of the one listed for the '99. Hopefully it all works because it is numbered for "up to '98" but it installed perfectly and the hall sensor pickup lined up properly. Here are some pictures comparing it to the other chain which was a stock replacement.

I didn't want to end up putting the "factory fix" adjuster or risk breaking that smaller chain because of the added power of the engine (probably would have been fine) but the heavy duty Cloyes C3211 was just immensely better all around!

Sprocket is literally double the thickness

Both are true roller chains but the rollers on the Cloyes are double size! Very nice product.

The chain was also tighter but just enough slack to install it. I put 2 drops of blue locktite on the cam sprocket bolts and tightened them to 22 ft lbs.

The crank sprocket went on solid with a 1 1/2" pipe

It takes TIME to build a motor! All the little things that can come up and surprise you.

Had to order the timing cover and install the oil pump after welding the pickup tube in place.

Welder broke so I got an exhaust shop to zap it. 66 ft lbs on the pump bolt. Day trip to drop welder off.

Cleaned and painted the pan (didn't want the aluminum to be able to oxidize anymore).

Installed the pan and used Permatex "Right Stuff" in the corners which is one step above the Ultra Black. The Right Stuff is the same formula as Toyota FIPG from what I hear.

Drilled the pushrod holes in the head for more angle since I'm using 1.6 rocker arms. The one on the right is drilled to 1/2" and elongated toward and from the valve. The hole on left is stock.

You can see 2 of the rocker arm studs which are almost removed. Those are the stock ones to be pulled out. I haven't installed the correct adjustable ones yet.
