222rwhp! boy is my face red.
something is definitely not right. I have a stock bottom, stock headed smog 360 in mine with just a street dominator intake, edelbrock carb, shorty headers, and a lunati cam
[email protected] and it made 276hp to the wheels. i think your single exhaust is choking it down big time. I would run dual 3" off the manifolds and see what that does. then an intake swap as was stated before.
