Crawled up under the car today! Still has stock exhaust on it, checked air filter, just a regular paper filter. Pretty sure it has 2.73 gears on it. Bumped up the timing to 13 degrees today! defenitely feeling a big difference on throttle response! This 5.0 defenitely beats that modular 4.6 motor! This car is a keeper not to mention it's a convertable!!
