Hard Starting?

[Timbo]

Can anyone recommend a Good high torque mini starter? I am looking into the summit starter? ....After running numerouse voltage checks and having my battery checked and checking out ok, I figure if it was my alternator my battey would eventually drop down in voltage or die..... ! I am reading well over +30 amps (my vdo gauge only goes to +30amps could be more) when first starting the car and then drops down to about +3-4 amps when on the road. At a stand still with everything off, My battary reads about 12.6 volts and at cranking over the engine it reads 9.8volts and after it starts and is running at an idle it reads almost 13 volts. So I figure I would start with starter!..... I feel a heat sheild wouldn't really fix the proplem depending on the style of sheild I wonder if it would deflect the heat or hold it? So I figure I would start with starter and work from there! Any recommendations would really be a big help! I have a 351w with gt40 p aluminum heads and a mild cam. After looking into them a little, I found the price range very wide! Any help would be great! "Thanks" in advance!
