                My Combo I was running in my 71 scamp,

                360 eng stock stroke,
                KB pistons 10,7 ,
                eagles rods,

                crane roller rockers,
                Comp solid flat tappet 555 lift,
                Digital 6 MSD box and dist,
                Wiend dual tunnel Ram and 2# AFB comp sers carbs 500s .
                Car #s 3000 lbs me in it,
                4 spd with the 833 trans pro shifted by liberty.
                4.88 gears, w 28 x 10.5 slicks.
                Best run 11.50 @ 119 mph 1.60 60 foot, 1/8th 7.45 ,

                It was a great combo may have ran faster with single Carb set up but I loved my duals. I am now building a R3 59 deg block trying to get into the 9s with the stick car.[​IMG]

                  It has full tubs in it, stock frame rails, ladder bars and coil over shocks.

                  the 8 3/4 has been narrow 2" on each side, there is plenty of room for bigger tires but i need to get rims with more backspacing, the center lines on the car have 4 7/8 ...really needs 5.5 or 6 BS to move tires in a bit....

                  if you minitub and move the springs and with the correct back spacing you should be able to get a 10 inch slick on your dart.

                  Guess it's finally my turn. First run off the trailer with new combo: 11.12 @ 118.6 and 7.02 @ 97 mph!! I'm still high!! I didn't get to make any other runs as I don't have a rollbar in my full interior street driven 68 Cuda notchback! I was totally blown away, but I knew that when I had to hold on to the steering wheel because it left so hard and pulled in 3rd on an Indy Headed 440 64 Dodge Candymatic clone I was in for a good run. I had people coming over scratching their heads, and to be frank, I was too! Dam this feels good!!!!!!:toothy10:


                  My combo:
                  68 Notchback Cuda, full interior, street driven

                  4000 stall Ultimate conv.
