Actually, your main problem can be tracked to three things:
1. Airflow, both intake and exhast. Having a 180 degree bend in your exhaust really sucks.
2. Programming. Its proprietary-based (like many others) but its pretty much unhackable. The few companies that do that, charge pretty high and aren't developing any personal use programmers. Without being able to control fuel trim and other factors, its hard to really improve upon the engine.
3. The transmission is a bitch. It sucks right around 28.5% of power IIRC from the engine. So stock, you're barely putting 171-179 at the wheels with the HO motor. It also can't handle too much more power, right about 300HP at the crank stock. Anything past that, and you're risking completely destroying the tranny.
Fastest 1/4mile in a NA LH car is Tom, at right around 14.216 or something like that.
