i have a 305 engine in an 84 camaro. when i take off the car will fly and then it acts like it dont wanna shift . i take off some pedal pressure and step on gas again itll shift. whats the deal?? also when i start my car when it sits for a day or so the belts squeal like hell until the belts warm up... i put chrome pulleys on would that be the prob? or is sumthing else wrong? thank you
