Kinda depends on a few things if you can spin them or not.
When it was 90 degrees out on cement I couldn't spin the tires. Well the PSI was a bit low and the tires were new and I only had LTs and exhaust. I raised the PSI in the tires and they spun pretty easy.
After I added the 3600 converter from yank, there is absolutely no issue anymore ha ha. I added drag radials, so that fixed that problem for now.

You should be able to break them loose. You just floor it from a standstill on the street and it wont spin? I wish I had that problem..
seriously the few off the lines ive done its embarrassing cuz my tires wont catch til im in like 3rd gear so i look like im standing still with a stock ls1 but when they catch im gone. haha, damn i love my car i think i will go for a drive.
When my WS6 was all stock with 3.23s the tires would just bark a little bit and go. It ran 13.3s like. So with 2.73s I could see it not spinning at all.
Also the headers probably make it harder to spin from a stop due to the loss of very low end power than comes from the decreased exhaust velocity at low rpms. And 2.73s with a stock stall is all about the low rpms.
A stall is what you need. A good stall will not only help the problem you have of not spinning, but it will also create a new problem that is spinning too much.
