Hey, thanks for all for the input on "HEI or points". I think I'll stick with the HEI and problably go with an aftermarket coil and module. My timing problem: I cannot get more than 10 degrees of centrifugal advance. My HEI has an aftermarket weight/ spring kit (the third) and none are allowing more than 10 degrees, no matter what spring set I use. I have taken the HEI out, removed cap and rotor and manually spun the weights out. It seems that the narrow leg of the weights "bottom out" against the center plate BEFORE the pins reach the end of the slot. I have verified from several sources that I have the weights/ plate installed correctly. I don't have the original weights to compare their full range of motion, but my tech book tells me that this HEI, stock, should give me 20 degrees of cent. advance. ALL aftermarket sets that I have tried do exactly the same thing. Without the weights/ centerplate installed the pins WILL bottom out, so I know the distributor mechanicals are functioning correctly. Has anyone had this problem with afetrmarket weights or am I overlooking the obvious? I am at a total loss. HELP!
