I changed my advance springs, used the second to fastest set up, one light gray and one light blue, much thinner than the springs coming in the distributor from factory. Now the advance is excelent, still, I can try the fastest set up, two light gray springs( take out the light blue), no detonation/pingling, so it is not over advanced. I also changed the total advance bushing from the factory 21 to the 28 degree one. Works oK. The pick up is amazing, I still have to adjust my carb idle, to it's better calibration, as well as the initial advance, just needs some fine tunning. MSD guys told me they send the dist from factory with the slowest set ups for safety. I think, the best approach will come out after a cam is installed. I am very happy anyways, the ignition system is made the car 500% better. Has anybody made a cold box for a carburetor? I am thinking about building one for the Weber 32/36. I can get a top and bottom air filter housing, close it with metal all around(as if a filter) except for the front, and connect a hose to the front of the car. I think I would have to use a filter at the front, like the EFI filters, right? or shoud it be positioned(filter) halfways through the hose to the cold box? Coldboxes are supposed to help performance.
