I'd like to hear opinions on the mini hei. Specifically, is the fact that the distributor shaft smaller a problem? It seems to me that the shaft needs to be the correct size ~0.49 otherwise, the oil pump won't support the side load of the gears. This would also seem to be a problem with the large hei as the lower part of the shaft has a wobble joint. How about pressing a bushing onto the disty shaft of the mini hei to bring the diameter up to 0.49?
