Have '69 GS350 with 212...all else stock except Pertronix and Edelbrock 750 carb. I am getting 12-13" vacuum at a 750RPM idle. Is this typical of this cam? I was expecting a little more than this. I have a stock converter, anyone know the stall speed on a stock piece? Will I gain any performance with a higher stall and if so what stall speed? How have you set up the timing? I have set to about 10deg initial but don't yet know overall...it is a stock distributer...any advice on modifying curve or what total timing I should have?
Here is a couple of threads that have already covered a lot of these issues. http://www.v8buick.com/showthread.php?s=&threadid=8021 http://www.v8buick.com/showthread.php?s=&threadid=7650 750 idle in park sounds a little low for that cam...... I think mine idles like that in drive. I do have a 2400 stall converter also.
