Go down on your pressure to 15 psi and do a good burnout. Make sure you are not sitting in the water box also. Pull out of the water a little. Do you have a line lock? If so, set it and shift from first to second during the burnout. Make sure you are getting some good smoke from the tires. My burnout plays a big part in my 60'. Don't change any of your combo until you are for sure the cam and converter are the culprit.

I launch off Idle, try doing all different things to get it to 60'..I hear a lot of guys launching at 2300, might be the sweet spot. It could be those fat *** 15x10's you are running..doesn't that even raise the gear ratio more? You might be closer to a 2.73 with those tires & that ultimately could be the problem 
1) I'm thinking that you have a tight converter. I bet a little shot would really wake the thing up.
2) Even with your bad 60', you're times seem way off. Unless you're running in some crazy high DA. You should be trapping at least 114 mph.
I have the same rims and tires. Stock cam, stock suspension, but 3.42s and I'm going 1.60-1.62 on motor all day long. I'm running ~20 psi. The radials like tire pressure. On motor, I launch around 3000+ rpms. Car hooks great. IMO, you should be launching at around 3000-3200 rpms and if the car isn't hooking then you need to address your suspension. Invest in some relocation brackets, LCAs, and SFCs. (I still need to do that myself)

I do this to a T every time I race it.
The car has subframes, no front sway bar but stock rear suspension.
All I can think is this thing is not making any power...... It was tunned by a advertiser on here so it should be good.
This same converter was behind my 422 in my other car with zero suspension and just a deleted sway bar and only cut 1.6's....... Maybe a combo of a tight converter and a poor cam choice. I am pretty bummed about this and getting burnt out.... The car should have picked up a ton from a 12.60 time stock.....
