Mid 12's with a 318 head 360?

My Harley Drag bike ( Ironhead Sportster) , is running low 7s (1/8) to me, that's fast, as it's completely streetable, and was my Daily here in Tampa for months. I'm impressed by his numbers. In fact, I think that's kinda Wicked!
well, that 7.20's is fast but it is no street car. It's strickly drag. I like Mopar joe's content and we chat now and then.
