What will my 68 Dart 408 run in 1/4 mile?

Well i checked with Summit and they said I could return my MT drag radials so I ordered some MT Sportsman Pro bias ply. Bopefully that'll help ease the harshness of my launch a little. I really don't want to swap my clutch right now and I just setup my rear end .

It's not going to be ideal for drag racing but it'll be fine hopefully for the 3 or 4 times I go this year.

I didn't read the whole thing (sorry if this was touched on already), but if you are looking for a more dragrace oriented street slick, try Hoosier Quick Time Pro's. They hook WAY better than the MT Sprotsman Pro's (I've used both), and they last longer too. The setup I used them on was a sprayed 360 I ran in Colorado at Bandimere Speedway (5800', DA was usually 9000+ feet), ran high 11's on the MT tires, and 11.1's on the Hoosier QTP's, no other changes. I was spraying a 180 shot out of the hole with a 727 manual valvebody auto...so probably similar shock to the tire as hitting it with a clutch. Just food for thought.

By the way, my guesstimate would be you run high to mid 12's the first time out. There is 11 second potential for sure, but it will probably take some tweaking.
