1/4 mile times

No offence, but it sounds like a maltitude of issues & mis-matched parts, with the .509, it'll never have much grunt down low with that junky converter, you also need to make sure the timing is dialed in (very important with that cam), i'd set it up for 20* int. & 36* total, all in at 22-2400 RPM. I'm sure the car hooks fine with the power/torque its looseing. Just trying to help.
