Good points (pun intended). On the parts board I have a nice distributor and like new wires for sale too ;-)

Re: Should I just go HEI

Thank you both. I thought about using a t off the pvc, but it is such a big hose that I would need to reduce the size somehow. Not by the truck, but I guess that's the manifold vacuum point that was referenced.

I've checked the manifold gasket with carb cleaner, and did not note a difference. Will check the shaft. The wires, cap, rotor, points, and condenser are new. Springs look ok, but who knows.

Compression test, all cylinders just over 120, but #5 is 90. Same results when tested wet. Was asking in another thread if I can ignore the one bad one and still get it to run ok. Never really got an answer. A cylinder rebuild is beyond what I want to spend.

I've a question about setting the points, found a pic on the internet that looks like the adjustment is from the lower portion of the points (in your pic above). But I noticed that the mounting screw hole for the points is long, not circular, meaning the points can move towards or away from the shaft (upper side of points from your picture). Hope that makes sense. Anyway, now I'm confused. If I adjust the long hole, it will only move where the points contact the shaft lobe. So are there 2 adjustments?

Going to tackle it weds, so I have some time to figure it out. Maybe U-tube is my best option.
