When I put the cam in ... I went from 14.35 to low 13's.
Cam wasn't the only thing that went on at that time.
At SBSO it wasn't running right. I was having horid problems with it. I have it idling like it should now. You can hear a little bit of lope, but not much. My exhaust (the one I run around with) is pretty quiet typically speaking though. It's the normal flow40 single in/dual out dumped in front of the axle. I think with a better exhaust you could prolly hear it lope a lot better.
It's a 216/220 .525/.532 114+2 I'll sell it to ya for what Hay Hauler is going to sell me his for.
