OK, I know.  This has been discussed over and over and I have read other posts and opinions on other websites.

I have an electronic distributor with 19 total crankshaft advance degrees.  The only way to increase that is using a file on the stops.
So what TOTAL do I run?  

Lets say you recommend 35 degrees, that means I need 16 degrees initial..  kinda steep??

QUESTION 2:  I have 3 sets of springs to choose from:  1)  All advance by 2500 rpm  2)  All by 3800 RPM 3) All by 5500 RPM

OK guys...Recommendations please!!

Auto or manual, do you have a standard cam, standard compression,  fuel type, altitude may have a bearing as well...  I would say you're going to be at 36 total, of course check under load to make sure its not pinging. You will have quite a bit of advance at idle but it will probably give you strong vacuum, make sure you're on ported vacuum advance. Also make sure you dont have too much vacuum advance , it will probably pull into the low 50's at cruise . I think you should be fine with all in at 2500 rpm.

Manual transmission, 5 speed Mustang.  I have about 9.5:1 compression and a warmed over cam.  Don't know the specs, but I bought it from Mummert based on his suggestion.
