another how quick do u think? yeah I know.

So I took my wife for a ride in my dart for the first time since I got it running again. I was getting on it pretty good, after we got home she turned to me and asked how fast do u think it is. To tell u the truth I don't have any idea I told her. I used to think maybe in the 13s ??? But I have'nt had it down the track yet. She only asked how fast I thought it was because a friend of ours has a mustang he says runs 12's when it's running. I have'nt seen it run yet, but maybe this summer. So anyway if u feel like sharing your input here it goes. My car is a 68 dart with a small block 392 stroke engine. It's a 318 with a 40 over bore, 4 inch scat crank, scat I beams, forged icon dished 23 pistons, rhs heads with 2.02 intake, headers, 2.5 exhaust, xe284h cam, hughes roller rockers, small 162 b@m supercharger, 750 double pumper, mp distributor and orange box, 4 speed, 3:55 gears. ss springs. I know getting it to hook up and go strait are all key to getting a good time, but this is just assuming it does. I know it's not the fastest car or the best combo, I'm just curious.
