Chevy starter cranks really slow

I just bought an 81 Chevy SWB truck, 106,000 miles. It has several problems ,but I just replaced the intake manifold (edelbrock) and carb. (holley) and now my starter seems to turn over very slowly, like
something is binding. I just replaced the battery, no change. Can a worn out starter turn slowly or can this be related to the work i just did. (ign. timing etc...) It seemed to turn over normally before I worked on it.

Check your connections. Maybe you have a loose ground or connection to the starter itself.

Well I checked the starter and thought for sure i had found the problem. The solenoid screws had fallen out and the short cable going from the solenoid to the starter was over halfway broken and frayed. figured this was the problem, it wasn't allowing enough amperage to get to the starter. put a new starter on it this morning, same problem. it actually sounds worse. i checked the ground going from the battery to the alternator bracket, it didn't seem like a decent ground so a ran an additional cable from the intake manifold to the alternator mt. bracket. no difference. i have .1 ohms from the starter to the intake manifold . running out of ideas

If the meter is correct, you've found the problem. Voltage equals current times resistance. If your starter is trying to draw 200 amps because it's turning so slowly, 200 amps times 0.1 ohm equals 20 volts. How big is the battery?
The problem is that ohmmeters aren't very accurate at very low resistances and, therefore, not very useful at high current. Try measuring the voltage from the actual negative battery post, not the cable terminal, to a clean grounded spot on the starter, while somebody actuates the starter. If you have more than a few tenths of a volt, there is one problem. Now measure the voltage from the actual positive battery post to the actual terminal on the battery while the starter is being actuated. Same thing--more than a few tenths of a volt and you have another problem.
Good luck and let us know what you find.

I'd check your timing. Sounds like it might be too far advanced. -- Old Crow "Yol Bolsun!" '82 FLTC-P "Miss Pearl" '95 YJ Rio Grande BS#133, SENS, TOMKAT, MAMBM

I have noticed an increase in cranking speed when a new starter was installed BUT you indicate that this is a new phenomena that wasn't evident before you did the work you describe. The timing can have this effect. Did you use a timing light?

Thanks for the input everybody, It was the timing.
Now I have to figure out why it sometimes pours out black smoke, like its getting flooded with fuel. It did this with the old carburetor and fuel pump. I replaced both and it still has the same problem. Well if it isn't one thing its another...
