I'd check your timing. Sounds like it might be too far advanced.

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

Have you checked the selenoid itself?

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 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...
