Hoping for some advise on how to set up my distributor.  I purchased a MSD Pro-Billet corvette specific distributor with tach drive.  I can adjust the amount of centrifical advance and how fast the advance comes in by changing springs and bushings.  I was wondering how much advance I should allow for and by what RPM it all needs to come in at?  Any help would be appreciated.

try a total of 24"built in"degrees and with a 10-12 degrees initial setting that will give you a total of 34-36 degees,you will want it all in at 2800-3000 RPM, I recomend you have it spun on a distributor machine, if it has a vac.adv. they can adjust it to.

thanks for the help.  I put the bushing that allows for 25 degrees of centrifical + the 10 initial, should be able to get that 34 - 36 no problem.  The springs I am using should allow full advance around 3000 rpm.  After I road test this new set up I will let youall know how it worked out.  Thanks,
