Another 1972 dart swinger

The trans, rear end, brakes steering and suspension all works but has 118k miles on it. Heads and carb need a rebuild.
The plan is to rebuild the heads, put a four barrel on it with headers, re ring it, new cam and timing chain and drive it around while working on one thing at a time. That's not how things went.

Here's what it looks like when you run old gas thru your engine.IMG_20160310_190121974.jpg

Timing chain is badly worn, the oil drip tab bolt does not have a hole thru the bolt holding it on, it does now. I would say not having the hole accelerated wear, just my opinion.IMG_20160323_152937267.jpg
