Shaner Posted April 28, 2008 Share Posted April 28, 2008 Hi everyone. Last weekend I dug into my Pro-comp ready to run distrib to see about swapping springs out on the advance weights. This is a non-vac advance model 8000 series MSD type. I got the base plate off and the weights and springs are huge compared to a HEI style. I've done some searching around here and on the net and can't seem to find out if this is a brand specific thing or a model thing. Can I swap out springs on the advance for the HEI style springs or can I swap the advance arms and springs and have it work? The weights are alot more in weight(I didn't have a scale to throw them on) and I'm cautious that if I put the HEI type springs on they won't hold the weights in at idle. Also a warning for others that may be buying or using one of these units, I found the ignition module was not screwed down fully on the base plate! Someone during assembly had used mismatching screws to install the module and the module was not keeping contact to the base plate. Wonder why the motor was cutting out on me??? Thanks for the help!!! Shane Quote Link to comment Share on other sites More sharing options...
