Maybe it is possible to retrofit something into the stock distributor. I don't know who originally cam up with the idea of the distributor that tom uses but you think its possible over all these years they would have thought about trying to fit a modern HEI system into a stock layout? I don't have a spare module in front of me but physically i do not think it would fit in the stock distributor. Possible a way to install a pickup and make the module external like lots of modders do.
