11 sec. build cost?

Right now it has the 7 1/4 rear with 2:73 gears so I have been to embarressed to run it. I think this spring I am going to take it up there before I put my other rear in it with 3:55's just to get a baseline. I have done a 12.6 in my dads mustang so I know what a 12 second ride is going to feel like and I am guessing my dart with the 2:73's is MAYBE a 14 second car. With the new rear and some better tires I would hope to be down in the 13's. I think I have decided to just keep building my dart now until I get to the low twelves then see where that puts my drivability. The trailer and truck for tow is not an issue. I am very interested to see what my dart turns now though and hopefully it will surprise me in a good way. The track opens in April I believe so I'll keep you guys posted on what it runs with the highway gears. I was hoping to get the new rear in over my christmas break but the intake and carb swap turned out to be a complete pain due to hunting down bolts and frigged nights in a pole barn with no heat.
