63 chevy...not getting fire

[nathan5830]

i bot a 63 chevy with a 230 strait six, and originally with a 3 on the tree, but wen i bot it, it has a 3 in the floor...vin says its a 72 saginaw

any way.... its gettin fuel, we replaced the coil, dist, cap, rotor, wires, plugs, and put the firing order right(the original owner had a ford coil, ford cap, and dist, and had it in the wrong firing order)

with all the new stuff, she still dont spark....

wat do yall think is wrong with it
