Dyno run/ missing out maybe? Low hp/tq

I'd focus on ignition timing FIRST! If you street drive the car, total timing method is a rotten way to set ignition.

That camshaft and low compression, get the car hot, slightly loosen dist clamp and twist dist body clockwise a bit. if it picked up RPM, reset to idle point say 800-850. Shut off and try to start, if it starts OK, do it again. Find point it strains or kicks back on the starter. Back it off from the strain level and put a timing light on it. Note the number.

Total timing, it may take 40+ if it's low compression. Maybe start at 36* total and feed 2* in at a time until you hear it ping. Find the point it pings and back it off a couple degrees. Depending on the distributor, it may take 4000rpm to find the point all the mechanical advance is applied. Reading plugs can be helpful, blackish speckles on the porcelain is not good.

Once you have those two timing numbers, initial and total, you can dial in the distributor so it works well with your engine. I wouldn't be surprised to see the engine wanting 20+* of initial/idle timing. The engine should idle in the 850ish range. DO NOT look at any old mopar factory service manuals because those idle timing numbers, usually TDC to 5BTDC, are garbage for a car that doesn't have to pass smog certifications.

Then tune up the carb idle settings. Use a vacuum gauge to set the idle mix screws.
