How much does this kit actually help?? Because my 1990 5.0 is basically stock. Except I have shorty bbk headers, bbk off road xpipe. And a bbk cold air. Really would like to know before I pay this much.
This kit will surely wake your car up. By far one of the most popular kits on the market. Not only will it give you increased performance, the sound of a cammed 5.0 cant be beat, This kit is designed to make 350 horsepower and 370 ft. lbs torque at the crank. your car is probably only making about 220 at the crank now with your listed modifications.
