David, that's a good respectable time for your 71 Electra with it being stock with nothing but exhaust. My car, with only exhaust modification ran a best 15.55 in Milan, MI in 2003. That was the only time I ran it that year. Last year, I was able to get it to 15.10 with a posi and some sticky tires that were WAY too tall. I'll try it again this year with my stock tires to see if I can find the elusive 14's I did some transmission work and recurved the distributor. Just some minor things, but all I have to do is get another tenth out of it and I'll be happy. A 4700 lb convertible running 14's with only minor mods should be fun!
