One freak bone stock manual trans 2000 Camaro SS (except the PCM tuning) makes 349 rwhp and runs 12.30s. I have a customer in Houston that ran 11.55 with his A4 2002 TA, never had a valve cover off. But, some won't even go 13s. I don't doubt Ford and MOPAR are the same way.

Sounds reasonable. In '94 I bought a new 25th Anniversary T/A w/ LT-1 auto trans and 3.23's. Bone stock I got it to 13.96 @ 99.6. Never could break 100. There was always a few others at the track that were also stock and there's were usually .2-.3 slower. They all doubted mine was stock.
I agree on the LS1's. Ive never driven anything but a 5.3L truck but for what it was, I was impressed. A friend of mine just bought a '06 Z06. He's foolishly
said I could take it for a spin. Can't wait!
