My best was a 12.54 @ 110, with a bad 1.87 60'. I have the TKO 600 with a 2.87 1st and a .82 overdrive. Great trany, I have a 256/260 duration cam and got 18.75 MPG on a 300 mile trip. I am still hoping for low 12's and maybe a high 11's, once I can figuer out how to launch!!!
Some pictures in the link of the tunnel mods I had to make.
