Wasn't happy with the way the Pig was running, just sounded a little rough at higher (3K) RPM. Couldn't tune it out. So I swapped distributors. Took out the '76ish non-ca vac advance with Pertronix and put back the 60 series bigcap. Fixed everything. I h8t the hold-down bolt for the bigcap, I can even reach it through the fenderwell and it's still a real PIA to get started.
I don't know if there was something wrong with the old dizzy or if the bigcap is just that much better.
