Hi there, I know you must have answered this question before and probobly know exactly what the problem is as well as the solution.
The car seems to take off in first gear just fine. Once the car is cruising normal and I accelerate just a little too hard the engine makes a rattling noise and the car doesn't have as much power. If i accelerate softer the noise seems to go away or is simply covered up by the noisie exaust. Has a 289. Other then this and some suspension issues and break light problems,car is running GREAT!
