I'm taking my Mustang to the track (any guesses on how Fast)

[68Falcon]

I'm taking my Mustang to the track nexts weekend. Well I'm going to the track this weekend but I'm racing my Falcon. So the weekend after that I will be taking my Mustang. I just wanted to see what you guys think and see how close you guys get. I'm bringing my street tire and some M/T drag radials. To see whats the difference between the two. I'm only thinking 13.40's

Here is my set up
It is 69 351W . It's bored .030 with 69 351 heads. Also has a hydraulic flat tapped Crane cams duration @050 216in 228ex. valve lift .484in .512ex, 1.6 Scorpion roller rockers, MSD distributor. Moroso spark plug wires. Edelbrock RPM air gap intake with Holley 750 Double Pumper. It has a C6 trans with a TCI 2800 stall converter and a TCI deep trans pan and an 8.8. The 8.8 has strange 31 spline axles with C-clip eliminators and Richmond 3.73 gears with a Richmond spool and a Granatelli Rear end support.
